Question

which plants utilize a specialized carbon fixation enzyme and a unique cell structure to reduce the problems of photorespiration? multiple choice desert arctic c3 c4

Explanation:

C4 plants have a specialized carbon - fixing enzyme (PEP carboxylase) and a unique cell structure (Kranz anatomy) that helps reduce photorespiration problems. C3 plants are more prone to photorespiration. Desert and Arctic are habitats, not types of plants defined by carbon - fixation and cell - structure related to photorespiration reduction.

Answer:

D. C4
