What are C3 plants examples?
C3 vs C4 Plants
| C3 Plants | C4 Plants |
|---|---|
| 95% of the green plants are C3 plants. | 5% of the green plants are C4 plants. |
| Examples include rice, wheat, oats, barley, cotton, peanuts, tobacco, sugar beets, soybeans and spinach | Examples include Maize, Sugarcane, pearl millet, sorghum. |
How do C4 plants differ from C3 plants?
C4 plants—including maize, sugarcane, and sorghum—avoid photorespiration by using another enzyme called PEP during the first step of carbon fixation. C3 plants are limited by carbon dioxide and may benefit from increasing levels of atmospheric carbon dioxide resulting from the climate crisis.
What are C3 plants and C4 plants?
10. C3 photosynthesis uses the Calvin cycle only for carbon fixation catalyzed by Rubisco, inside the chloroplast in mesophyll cells. While C4 plants photosynthesis activities are divided between mesophyll and bundle sheath cells where carbon fixation is catalyzed by phosphoenolpyruvate carboxylase (PEPC).
Is C3 a tomato plant?
C3 plants are those, in which the first stable product of carbon fixation is 3-carbon compound 3-phosphoglyceric acid (3-PGA). Tomato is a C3 plant.
How do C3 plants respond to higher concentration of CO2?
C3 plants respond to increased CO2 concentration by increasing rate of photosynthesis.
Which is CO2 acceptor in C3 plants?
RuBP
RuBP (5C) acts as the primary CO2 acceptor in C3 plants, leading to the formation of 2 molecules of 3-PGA (C3 acid). The enzyme RuBisCO catalyses the reaction.
Which is more efficient C3 or C4?
C4 plants are more efficient than C3 due to their high rate of photosynthesis and reduced rate of photorespiration. The main enzyme of carbon fixation (Calvin cycle) is RuBisCO, i.e. ribulose bisphosphate carboxylase oxygenase. It has an affinity for both CO2 and O2.
