Up Next. Carbon dioxide enters from the atmosphere to the mesophyll cells through the stomata. The general equation of photosynthesis (6CO2 + 12H2O → 6C6H12O6 + 6O2 + 6H2O) is similar in both C3 and C4 plants. Learn the difference between C3 and C4 plants here. C4 plants uses C4 cycle or Hatch-Slack Pathway for the dark reaction of photosynthesis. C3 photosynthesis is thought to have arisen nearly 3.5 billion years ago. C3 cycle is evolved about 2.5 billion years ago. Due to this fact, C assimilation is less in C3 plants while C assimilation is high in C4 plants. Hence, it is also a difference between C3 and C4 plants. Biology is brought to you with support from the Amgen Foundation. C3 plants uses C3 cycle or Calvin cycle for dark reaction of photosynthesis. C3 and C4 plants incorporate CO2 into 3 and 4 carbon compounds. Compare the Difference Between Similar Terms. About 85% of plants are C3 plants, and 15% of plants are C4 plants. It evolved as an adaptation to high light intensities, high temperatures, and dryness. C4 Plants: These plants in addition to C3 cycle, uses an additional dark reaction pathway called C4 cycle. The main difference between C3, C4 and CAM plants is the way these plants minimize water loss. 5. Carbon dioxide fixation. This is the currently selected item. Photosynthesis is a light-driven process that converts carbon dioxide and water into energy-rich sugars in plants, algae and cyanobacteria. The optimum temperature of growth is high in C4 plants. Photorespiration. C3 plants uses C3 cycle or Calvin cycle for dark reaction of photosynthesis. The first stable product formed in C3 cycle is a three carbon (3C) compound, hence the name. Does the optimal temperature increase for photosynthesis in C3 plants as atmospheric CO2 concentrations increase, as in green houses with supplemental CO2? 4. Table Showing C3 and C4 Plants Differences Table showing C3 and C4 plants differences. The key difference between C3, C4 and CAM photosynthesis is the way plants extract carbon dioxide from sunlight, which depends largely on the plant's habitat. Most of the plants follow the Calvin cycle, which is the C3 photosynthesis pathway.These plants grow in regions where there is adequate water availability. As the name indicates, they carry out C3 photosynthetic mechanism that is Calvin cycle. In contrast to C3 plants, the first stable product formed during photosynthesis is oxaloacetic acid, which is a four-carbon compound. 1. Unlike C4 plants, C3 plants consist of 3-phosphoglycerate with three carbon atoms. The optimum temperature for growth is low to high in C3 plants. C4 plants are less in number (about ~5%). Photorespiration. Furthermore, they have chloroplasts to carry out photosynthesis. C3, C4 and CAM are the three different processes that plants use to fix carbon during the process of photosynthesis. i really want these notes they are helpful to me, Your email address will not be published. Difference between Mesophyll Chloroplasts and Bundle Sheath Chloroplasts in C4 Plants, Plant Physiology: Difference between Topics. I’m very happy to get your pupplication, thank for all!! These plants show normal leaf anatomy. 2. Furthermore, photosynthetic efficiency of C3 plants is less than the photosynthetic efficiency of C4 plants. Therefore, this is the key difference between C3 and C4 plants. C4 plants are warm season plants, commonly seen in dry areas. C3 plants are less efficient in Photosynthetic energy fixation. Furthermore, C3 plants show less photosynthetic efficiency while C4 plants show high photosynthetic efficiency. C3 plants are less efficient when the temperature increases. When considering the structural differences, C3 plants do not have two types of chloroplasts and Kranz anatomy in leaves. 1. The physical separation cost a bit more in energy but conserves water very well so works better in warmer climates with intense sunlight. Chloroplasts dimorphic: Those in the bundle sheath are large agranal and those in mesophyll are small and granal. C3, C4, and CAM plants. C4 plants possess two CO2 acceptors (primary acceptor and secondary acceptor). C4 plants are less than C3 but they are efficient in carrying out the process of photosynthesis. The key difference between C3 and C4 plants is that the C3 plants form a three-carbon compound as the first stable product of the dark reaction while the C4 plants form a four-carbon compound as the first stable product of the dark reaction. The optimum temperature for photosynthesis in C4 plants is high. For C3 and C4 plants, the stomata are open during the day. Fixing carbon is the way plants remove the carbon from atmospheric carbon dioxide and turn it into organic molecules like carbohydrates. Furthermore, C3 plants and C4 plants differ from the first carbon dioxide acceptor. Majority of the plants (~95%) on earth are C3 type. The process of photosynthesis in plants is completed in two broad steps, a light dependent ‘. The atmospheric CO2 acceptor in C3 plants is RuBP (Ribulose-1,5-bisphosphate). Difference Between C3 And C4 Plants In Tabular Form. C4 plants have 50% higher photosynthesis efficiency than C3 plants. C4 photosynthesis is thought to have arisen nearly 12 million years ago; long after the evolution of C3 mechanism. It hypothesizes that C 4 plants have a greater N use efficiency (biomass production per unit of N in the plant) than do C 3 plants. On the other hand, C4 plants produce oxalo-acetic acid as the first stable product of the dark reaction. C3, C4, and CAM plants. C 4 Plants. Examples of C4 plants: Maize, Sugarcane, Sorghum, Amaranthus. The additional C4 step holds CO2. All plants use C3 as the basis but C4 plants have an additional step that separates the C3 & C4 cycles in space. C3 plants require an optimum temperature range of 18 – 24oC. It evolved as an adaptation to high light intensities, high temperatures, and dryness. 3. The main difference between C4 and CAM plants is the way they minimize water loss. Sort by: Top Voted. These competing reactions normally run at a ratio of 3:1 (carbon: oxygen). All of these plants are able to adapt to arid, high heat and light environmental conditions. In the light reaction, the chlorophyll molecules in the plants absorb energy from sunlight and synthesize energy rich chemical molecules such as ATP and reduced coenzymes (NADPHH+). The first reaction is the fixing of carbon dioxide with Ribulose bisphosphate into phosphoglycerate which is a three-carbon compound. The photosynthetic efficiency of C3 plants is comparatively less due the high rate or photorespiration. They are C3 plants, C4 plants and CAM plants. The C4 Plants lives as hot moist or arid and nonsaline habitats. Her research interests include Bio-fertilizers, Plant-Microbe Interactions, Molecular Microbiology, Soil Fungi, and Fungal Ecology. 5% of … Both C3 and C4 plants requires chloroplasts for doing photosynthesis. C3 plants carry out the Calvin cycle and produce three-carbon compound as the first stable product while the C4 plants carry out C4 mechanism and produce four carbon compound as the first stable product. 2003). This 3 minute tutorial discusses the differences between the three types of photosynthesis: C3, C4 and CAM. Photorespiration occurs due to the oxygenase activity of Rubisco enzyme. System flow of the comparison between C3 and C4 metabolic networks Both C3 and C4 plants synthesize carbohydrates.

C4 Plants are plants exhibits C4 pathway which is called as C4 plants. The photosynthetic efficiency of C4 plants is very high due to the absence of photorespiration. Carbon dioxide acceptor. The carbon dioxide compensation point is low in C4 plants (2 to 5 or even 0 ppm). -This gene can be found in sugar cane -Restriction enzymes can be used to cut out the SCR gene from sugarcane -The It is a four-carbon compound. Around 95% of plants on earth are C3 plants. The rate of translocation of the end-products of photosynthesis very low in C3 plants. The photosynthesis essential involves the synthesis of carbohydrates with atmospheric carbon dioxide, water and energy obtained from the sunlight. C 4 plants use the C 4 carbon fixation pathway to increase their photosynthetic efficiency by reducing or suppressing photorespiration, which mainly occurs under low atmospheric CO 2 concentration, high light, high temperature, drought, and salinity. C3 cycle is the first described dark reaction pathway. Vol.72, 1983 provide newand additional evidence that the action ofmercury vaporuponplants appears to beselective in nature (6, 9). There is a circle of bundle sheath cells with chloroplasts around vascular bundles by which C4 plants can be identified. Table 1: Features of C3 and C4 grasses There is more abundance of C3 plants as compared to the C4 plants. The reaction is catalyzed by PEP carboxylase enzyme. Occurs twice, first in mesophyll cells, then in bundle sheath cells. Photorespiration is altogether absent in C4 plants (if present very little). The carbohydrate product of both C3 and C4 cycle is a three-carbon sugar phosphate molecules called Glyceraldehyde 3 phosphate (G3P). ELEMENTS OF COMPARISON: C3 Plants C4 Plants: Meaning: These are plants whose first product after carbon assimilation from sunlight is 3 carbon molecule or 3- phosphoglyceric acid for production of energy. The present post describes the similarities and differences between C3 plants and C4 Plants.

Species: Cactuses and other succulents, Clusia, tequila agave, pineapple. RuBP can accept CO2 in both C3 and C4 plants. Growth of C4 plants begins when the soil temperature reach 16 – 21oC. C4 plants are more efficient in photosynthesis. Occurs once. C4 plants are more efficient when the temperature increases. CAM stands for Crassulacean Acid Metabolism (due to its first having been identified in plants of the family Crassulaceae). @. In C3 plants, the light and dark reactions of photosynthesis occur in a single location. in Molecular and Applied Microbiology, and PhD in Applied Microbiology. Sort by: Top Voted. C3 plants are defined as the plants that use the C3 pathway in the dark reaction of photosynthesis. Both C3 and C4 are types of dark reactions of photosynthesis. Not only that, C4 plants can carry out photosynthesis when the stomata are closed and under very high light concentrations and low CO2 concentrations. The key difference between C3 and C4 plants depends on the first carbon product that they produce during the dark reaction. Photorespiration. @. C3 photosynthesis produces a three-carbon compound via the Calvin cycle while C4 photosynthesis makes an intermediate four-carbon compound that splits into a … Overview and Key Difference Likewise, the Calvin cycle occurs cyclically while producing carbohydrates. -In order to turn C3 plants into C4 plants we need to remove the Scarecrow gene from a C4 plant and add it into a C3 plant. Subsequent steps are carried out in bundle sheath cells. C3 plants are very common while C4 plants are very rare. In C3 plants, both mesophyll cells and BS cells are photosynthetic, but the BS cells are elongated with fewer chloroplasts. 3. C4 plants may be better adapted now, as the current carbon dioxide levels are much lower than 100 million years ago. It is because of the occurrence of photorespiration in C3 plants. The major difference in C4 and CAM plants is when and where the carbon fixation initially occurs. However, oxygen generated from the light reaction can bind with the main enzyme of the dark reaction which is RuBP oxygenase-carboxylase (Rubisco) and carry out photorespiration. Whats people lookup in this blog: Biology is brought to you with support from the Amgen Foundation. What are C4 Plants Cancel Unsubscribe. A feature of C3 grasses is their greater tolerance of frost compared to C4 grasses. This is the currently selected item. LITERATURE CITED 1. Photosynthesis is the process that plants use to turn light, carbon dioxide, and water into sugars that fuel plant growth, using the … Engineering the C3 plants to C4 or CAM pathway can help scientist to almost double the biomass yield from the same resources. C3 can be seen in all photosynthetic plants, while C4 is followed by tropical plants and CAM by Semi-arid condition plants. In the light reaction, the chlorophyll molecules in the plants absorb energy from sunlight and synthesize energy rich chemical molecules such as ATP and reduced coenzymes (NADPHH+). They comprise about 85% of all plant species (Moore et al. Main Difference – C3 vs C4 plants. Compared to C4 plants, C3 plants are inefficient regarding their photosynthetic mechanism. First stable product in C4 cycle is a 4 carbon (4C) compound – Oxaloacetic Acid (OAA). So the only real difference between C3 and C4 photosynthesis is that between the light-dependent and Calvin-Benson cycle, there is an additional step where carbon is transported to the interior of the leaf. Thus, it is clear that photorespiration is a light stimulated process that consumes oxygen and evolves carbon dioxide. C4 and CAM plants are no like most plants, which are categorized as C3 plants, because they are more adapted to live in hotter environments where water is not readily available. Whats people lookup in this blog: Green plants are unique to possess the ability to fix light energy from sunlight through a process called photosynthesis. 2. There are essentially three different types of dark reaction pathways are operated in different plants on earth and they are named on the basis of the components of these pathways. Likewise, interaction with oxygen and carbon dioxide occurs at the same site on Rubisco. They are C3 plants, C4 plants and CAM plants. Majority of plants on earth are C3 plants (~95% of total green plants). Carbon dioxide fixation is relatively faster in C4 plants. Chloroplasts do not contain peripheral reticulum. Difference between C3 C4 and CAM plants SCIENCE LEARNING ACADEMY. Therefore, in order to prevent photorespiration, there are three different ways that dark reaction occurs in plants to prevent the meeting of oxygen with Rubisco. Then PEP converts into malate and then into pyruvate liberating CO2. According to Pima Community College, during photosynthesis, C3 plants incorporate carbon dioxide into a three-carbon compound, while C4 plants incorporate carbon dioxide into a four-carbon compound. In C4 plant is 30ATP. On the other hand, C4 plants have two types of chloroplasts, and they show Kranz anatomy in leaves. C3 requires cool and wet environments. Examples of C3 plants: Wheat, Rye, Oats, Rice, Cotton, Sunflower, Chlorella. While C4 plants are defined as the plants that use the C4 pathway during the dark reaction. In C4 plants, the bundle sheath cells contain chloroplasts. Loading... Unsubscribe from SCIENCE LEARNING ACADEMY? @. Photosynthetic functions occur in mesophyll and bundle sheath cells. C3 plants are those plants where the first product of photosynthesis is a 3 carbon compound i.e. No.C3 PlantsC4 Plants1C3 plants uses C3 cycle or Calvin cycle for dark reaction of photosynthesis.C4 plants uses C4 cycle or Hatch-Slack Pathway for the dark reaction of photosynthesis.2Examples of C3 plants: Wheat, Rye, Oats, Rice, Cotton, Sunflower, Chlorella.Examples of C4 plants: Maize, Sugarcane, Sorghum, Amaranthus.3First stable product in C3 cycle is a 3 carbon (3C) compound – Phosphoglyceric Acid (PGA).First stable product in C4 cycle is a 4 carbon (4C) compound – Oxaloacetic Acid (OAA).4C3 plants are cool season plants, commonly seen in cool and wet areas.C4 plants are warm season plants, commonly seen in dry areas.5Majority of plants on earth are C3 plants (~95% of total green plants).C4 plants are less in number (about ~5%).6C3 plants are abundant in temperate conditions.C4 plants are abundant in tropical conditions.7Leaves of C3 plants do not have Kranz anatomy.Leaves of C4 plants show Kranz Anatomy.8In C3 plants, the bundle sheath cells do not contain chloroplasts.In C4 plants, the bundle sheath cells contain chloroplasts.9In C3 plants, the carbon dioxide fixation takes place only at one place.In C4 plants, the carbon dioxide fixation takes places twice (one in mesophyll cells, second in bundle sheath cells).10C3 plants possess only one CO2 acceptor.C4 plants possess two CO2 acceptors (primary acceptor and secondary acceptor).11The atmospheric CO2 acceptor in C3 plants is RuBP (Ribulose-1,5-bisphosphate).The first CO2 acceptor (primary acceptor or atmospheric CO2 acceptor) in C4 plants is PEP (phosphoenolpyruvate)12No secondary CO2 acceptor in C3 plants.The secondary acceptor of CO2 (metabolic CO2 acceptor) in C4 plants is RuBP.13In C3 plants, the complete steps of dark reaction takes place in the mesophyll cells only.In C4 plants, the mesophyll cells will only do the initial steps of C4 cycle. In the mesophyll cell cytoplasm, CO2 first fixes with phosphoenolpyruvate (PEP), which acts as a primary acceptor. 2008. As a result, the δ 13 C Phytoliths value difference between C 3 and C 4 plants is much smaller ~ 3‰ compared to 16.9‰ difference between the source C 3 and C 4 plants. Difference between Mesophyll Chloroplasts and Bundle Sheath Chloroplasts in C4 Plants, @. The first CO2 acceptor (primary acceptor or atmospheric CO2 acceptor) in C4 plants is PEP (phosphoenolpyruvate). Sl. The optimum temperature for photosynthesis in C3 plants is very low. C3 plants are abundant in temperate conditions. RuBP is the CO2 acceptor in C3 plants while PEP is the first CO2 acceptor in C4 plants. Those rudimentary genes that formed the C4 pathways are also present in plants. On the other hand, C4 plants have Kranz anatomy in their leaves, and also they have two types of chloroplasts. Leaves of C3 plants do not have Kranz anatomy. @. Main or the key difference between C3 and C4 is that C3 are found in all photosynthetic plants and C4 are found usually in tropical plants. Szczepanik, et al. Study.com, Study.com. 4. In the dark reaction, these energy rich molecules are used up for the synthesis of carbohydrates with carbon dioxide. Chloroplasts monomorphic (single type) in C3 plants (usual granal type). About 95% of the plants on earth are C3 plants. The difference between C3 and C4 plants. The first stable product formed in C4 cycle is a four carbon (4C) compound, hence the name. Oxygenation of Rubisco works in the opposite direction to carboxylation, effectively undoes photosynthesis by wasting large amounts of carbon originally fixed by the Calvin cycle at great expense, and results in loss of carbon dioxide from the cells that are fixing carbon dioxide. C3 plants can perform photosynthesis only when the stomata are open. Thus, this is the summary of C3 and C4 plants. C3 and C4 plants are two types of plants using C3 and C4 cycles during the dark reaction of photosynthesis respectively. The key difference between C3 and C4 plants is that the C3 plants form a three-carbon compound as the first stable product of the dark reaction while the C4 plants form a four-carbon compound as the first stable product of the dark reaction. Leaf anatomy in C 4 plants: Leaves of C 4 plants show two type of cells viz. 6. The C4 Plants, evolved from the C3 plants, have high nitrogen and water use efficiency. Practice: Photorespiration. Table C-1. Available here  Enter your e-mail address. Approximately 1% of plant species have C4 biochemistry. Figure2. During the light reaction of photosynthesis, photolysis of water molecules occurs. C3, C4, and CAM plants all carry out the same photosynthetic functions.

(adsbygoogle = window.adsbygoogle || []).push({}); Copyright © 2010-2018 Difference Between. Originated about 12 million years ago. It is due to the photorespiration seen in C3 plants which is negligible in C4 plants. Below are the details. Both C3 and C4 plants fix energy from sunlight. For a considerable period of time, the C3 cycle was thought to be the only dark reaction pathway in plants. The difference is that the stomata are open at night to have a controlled release of water vapor to drive the upward pull of water and dissolved nutrients in transpiration. For the synthesis of glucose, C3 plants require 12 NADPH molecules and 18 ATP molecules while C4 plants require 12 NADPH molecules and 30 ATP molecules. Please Share with Your Friends... Green plants are unique to possess the ability to fix light energy from sunlight through a process called photosynthesis. The system flow of our analysis is shown in Figure Figure2.2. Photorespiration. ATP required 19. C4 plants are less than C3 but they are efficient in carrying out the process of photosynthesis. The main difference between C3 C4 and CAM photosynthesis is that C3 photosynthesis produces a three-carbon compound via the Calvin cycle, and C4 photosynthesis produces an intermediate four-carbon compound, which split into a three-carbon compound for the Calvin cycle, whereas CAM photosynthesis gathers sunlight during the day and fix carbon dioxide at night. Degree in Plant Science, M.Sc. C3 and C4 are two types of plants. C4 cycle is comparatively recent in origin. C3 plants are cool season plants, commonly seen in cool and wet areas. In Table 2 can be seen the differences in the percentage volume of air space of total leaf volume in C3 and C4 monocotyledonous species. Engineering the C3 plants to C4 or CAM pathway can help scientist to almost double the biomass yield from the same resources. Those rudimentary genes that formed the C4 pathways are also present in plants. The main difference between C3 and C4 cycle is the first stable compound produced by these reactions; the first stable compound produced in the C3 cycle is a three carbon compound called 3-phosphoglyceric acid (PGA) whereas the first stable compound produced in the C4 cycle is a four carbon compound called oxaloacetic acid (OAA). However, C3 plants are unable to carry out photosynthesis when the stomata are closed and under very high light concentrations and low CO2 concentrations. Examples of C3 plants: Wheat, Rye, Oats, Rice, Cotton, Sunflower, Chlorella. In C3 plants, the carbon dioxide fixation takes place only at one place. Perfect notes. The main difference between C3 and C4 plants is, C3 plants uses the C3 pathway and majority of plant son this Earth are C3 plants, while on the other hand, C4 plants uses the C4 pathway.
