In C₄ plants, the four-carbon compound that is synthesized by carbon fixation in the mesophyll cells A) reduces NADP⁺. B) combines with CO₂ to produce sugar. C) carries CO₂ to the bundle sheath cells. D) drives the synthesis of ATP. E) closes the stomata.

Question

Quizplus · Accepted Answer

In C4 plants, the four-carbon compound synthesized by carbon fixation in the mesophyll cells carries CO2 to the bundle sheath cells, where it is released for use in the Calvin cycle. This adaptation helps to minimize photorespiration and increase the efficiency of photosynthesis in hot, arid environments.
