A plant mutant that shows normal gravitropic bending but does not store starch in its plastids would require a reevaluation of the role of ________ in gravitropism.

Question

Quizplus · Accepted Answer

The presence of starch in amyloplasts is commonly associated with the sedimentation of statoliths, which are involved in gravitropic bending. Therefore, a mutant lacking starch storage but still exhibiting normal gravitropic bending suggests that amyloplasts may not play a critical role in this process. The options A, B, D, and E are not as directly related to the process of gravitropism as amyloplasts.
