C4 plants can do photosynthesis even in the closed condition of stomata. 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. 2. 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. C4 cycle is comparatively recent in origin. C4 plants have 50% higher photosynthesis efficiency than C3 plants. C4 plants produce more amounts of crude protein than C3 plants.

These competing reactions normally run at a ratio of 3:1 (carbon: oxygen). CAM plants are C4 so hold the CO2 taken in while the stomata are open. These plants show normal leaf anatomy. All rights reserved. Ribulose bisphosphate carboxylase (Rubisco) is the enzyme that catalyzes this carboxylation reaction in plants. The carbon dioxide compensation point is low in C4 plants (2 to 5 or even 0 ppm). C3 species also tend to generate less bulk than C4 species; however, feed quality is … C4 plants uses C4 cycle or Hatch-Slack Pathway for the dark reaction of photosynthesis. Compared to C4 plants, C3 plants are inefficient regarding their photosynthetic mechanism. CAM is a carbon fixation pathway that revolved in some plants. Difference between C3 C4 and CAM plants SCIENCE LEARNING ACADEMY. Leaves of the C4 plants … Sl. C4 requires tropical and dry environments. In C4 plants, the mesophyll cells will only do the initial steps of C4 cycle. C3 can be seen in all photosynthetic plants, while C4 is followed by tropical plants and CAM by Semi-arid condition plants. C4 Plants are plants exhibits C4 pathway which is called as C4 plants.

Moreover, RuBP involves in the dark reaction of both types of plants. In C3 plants, the light and dark reactions of photosynthesis occur in a single location. I’m very happy to get your pupplication, thank for all!! C3, C4, and CAM plants. 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 2008. (adsbygoogle = window.adsbygoogle || []).push({}); Copyright © 2010-2018 Difference Between. RuBP, a 5-C-compound. First stable product in C4 cycle is a 4 carbon (4C) compound – Oxaloacetic Acid (OAA). C 3 Plants. C4 plants are less than C3 but they are efficient in carrying out the process of photosynthesis. After the light reaction, the dark reaction starts and it synthesizes carbohydrates by fixing carbon dioxide. Enter your e-mail address. In these plants, carbon fixation takes place in the mesophyll cells that are just beneath the epidermis. C3 cycle is evolved about 2.5 billion years ago. @. Hence, depending on the way that dark reaction takes place, there are 3 types of plants; namely, C3 plants, C4 plants, and CAM plants. Plant Physiology: Difference between Topics. Furthermore, photosynthetic efficiency of C3 plants is less than the photosynthetic efficiency of C4 plants. Thus, it is clear that photorespiration is a light stimulated process that consumes oxygen and evolves carbon dioxide. C4 plants may be better adapted now, as the current carbon dioxide levels are much lower than 100 million years ago. Those rudimentary genes that formed the C4 pathways are also present in plants. As the name indicates, these plants carry out the C4 photosynthetic mechanism. @media (max-width: 1171px) { .sidead300 { margin-left: -20px; } } Both C3 and C4 plants require 6 molecules of CO2 and 12 molecules of water to synthesis one molecule of glucose. Difference between c3 and c4 plants table 13.1 Ask for details ; Follow Report by Nasirabdul811 04.06.2019 Log in to add a comment C3, C4, and CAM plants. These plants are mostly woody and round leaf plants. What are C4 Plants Moreover, a further difference between C3 and C4 plants is that the C3 plants fix carbon dioxide only once while C4 plants fix carbon dioxide twice. In C3 plants, the light reactions occur in … C3 photosynthesis produces a three-carbon compound via the Calvin cycle while C4 photosynthesis makes an intermediate four-carbon compound that splits into a … They are C3 plants, C4 plants and CAM plants. Moreover, C3 plants do not have Kranz anatomy in leaves, and also they don’t have two types of chloroplasts. C3 plants produce phosphoglyceric acid as the first stable product of the dark reaction. C4 plants produce fewer amounts of crude proteins than C3 plants. For a considerable period of time, the C3 cycle was thought to be the only dark reaction pathway in plants. The key difference between C3 and C4 plants depends on the first carbon product that they produce during the dark reaction. Subsequent steps are carried out in bundle sheath cells.14Chloroplasts monomorphic (single type) in C3 plants (usual granal type).Chloroplasts dimorphic: Those in the bundle sheath are large agranal and those in mesophyll are small and granal.15Chloroplasts do not contain peripheral reticulum.Chloroplasts do have peripheral reticulum.16C3 plants can perform photosynthesis only when the stomata are open.C4 plants can do photosynthesis even in the closed condition of stomata.17The optimum temperature for photosynthesis in C3 plants is very low.The optimum temperature for photosynthesis in C4 plants is high.18C3 plants are less efficient in Photosynthetic energy fixation.C4 plants are more efficient in photosynthesis.19Photorespiration rate is very high in C3 plants.Photorespiration is altogether absent in C4 plants (if present very little).20The carbon dioxide compensation point is high (about 50 ppm) in C3 plants.The carbon dioxide compensation point is low in C4 plants (2 to 5 or even 0 ppm).21C3 plants require an optimum temperature range of 18 – 24oC.C4 plants require an optimum temperature range of 32 – 55oC.22Growth of C3 plants begins when soil temperature reach 4 – 7oC.Growth of C4 plants begins when the soil temperature reach 16 – 21oC.23C3 plants are less efficient when the temperature increases.C4 plants are more efficient when the temperature increases.24C3 plants produce higher percentage of crude proteins than C4 plants.C4 plants produce fewer amounts of crude proteins than C3 plants.25The CO2 fixation is slow in C3 plants.The CO2 fixation is comparatively faster in C4 plants.26The rate of translocation of the end-products of photosynthesis very low in C3 plants.The rate of translocation of end-products of photosynthesis is very high in C4 plants.27The optimum temperature for growth is low to high in C3 plants.The optimum temperature of growth is high in C4 plants.28C3 cycle is evolved about 2.5 billion years ago.C4 cycle is comparatively recent in origin.
