Question

C4 plants occur more commonly in desert conditions because _____.
A. the stomata open at night and close in the day
B. they store carbon by incorporating CO2 into organic acids that are later catabolized
C. they produce carbon dioxide internally via photorespiration
D. they produce water as a product of their photosynthetic pathways
E. they can fix carbon at the lower CO2 concentrations that develop when the stomata are closed

Answer 1

Answer:

The correct answer is option E.

Explanation:

C4 plants are the plants that utilize the Hatch-Slack pathway or C4 carbon fixation type of photosynthesis process in which carbon dioxide into 4 carbon sugar to move to the Calvin cycle.

These plants are present more commonly in dry and hot climates such as deserts due to their ability to the fixed carbon at a low concentration of carbon dioxide and produce more energy when stomata are closed. Corn, pineapple sugarcane and many more are examples of the C4 plants.

Thus, the correct answer is option - E.
