Question

Plants using the C4 photosynthetic pathway

A) use rubisco to catalyze the reaction between O and RuBP.
B) have a lower rate of photosynthesis than plants using the C3 photosynthetic pathway.
C) divide photosynthesis between mesophyll and bundle sheath cells.
D) are mostly trees.

Answer 1

Plants using the C4 photosynthetic pathway divide photosynthesis between mesophyll and bundle sheath cells, concentrating carbon dioxide in the latter. They are more water efficient and faster in carbon fixation than plants using the C3 pathway.

Step-by-step explanation:

Plants using the C4 photosynthetic pathway divide photosynthesis between mesophyll and bundle sheath cells. Unlike plants using the C3 pathway, C4 plants concentrate carbon dioxide in the bundle sheath cells. The C4 pathway allows C4 plants to acquire carbon dioxide while losing less water and enables them to keep their stomata open for CO2 capture, especially in hot and dry conditions. This makes them more efficient in terms of water use and faster in carbon fixation than C3 plants.
