Question

even thoughvery few cell in a C4 plant carry out the biosynthetic calvin pathway yet they are highly productive can you discuss why​

Answer 1

Answer:

C4 plant have high productivity e because they have capacity to do photosynthesis in in high temperature and saturation at low carbon dioxide as compared to C3 plant. these productivity double as compared to C3 plant.

Answer 2

Answer:

Plant productivity can be estimated by the rate at which photosynthesis takes place. The amount of carbon dioxide in a plant is directly proportional to the rate of photosynthesis. In C4 plants, very few of the cells carry out the biosynthetic pathway yet they are highly productive for the following reasons.

• They have a mechanism that increases the CO2 concentration at the site of enzyme.

• Mesophyll cells are broken down in the bundle sheath cells that results in CO2 release which inturn increases the intracellular CO2 concentration .

• Rubisco functions as a carboxylase minimizing the oxygenase activity.

• Increase in photosynthesis make C4 plants more productive.
