How is photorespiration avoided in C-4 plants?
A) decrease the concentration of phosphoglycolate.

C) increase the concentration of ribulose-1,5-bisphosphate.
D) transport of carbon dioxide from the mesophyll cells to the bundle sheath cells.
E) none of the above.

Question

Quizplus · Accepted Answer

To avoid photorespiration, C-4 plants have a specialized leaf anatomy where the carbon fixation process occurs in the mesophyll cells first and then the carbon is transported as a four-carbon compound to the bundle sheath cells where the Calvin Cycle takes place. This separation of the two processes ensures that carbon dioxide is concentrated in the bundle sheath cells, avoiding photorespiration.
