A) They move away from the direction of gravity.
B) They settle in the direction of gravity.
C) They are digested by amylase.
D) They move into the root apical meristem.
E) They move into a root hair.

Amyloplasts

A type of plastid found in some plant cells, responsible for the synthesis and storage of starch granules through the process of photosynthesis.

Root Cap

A protective structure located at the tip of a plant root that shields the growing tip in the soil, secretes mucilage to aid in movement, and perceives gravity.

Final Answer :
B
Explanation :
Amyloplasts in root cap cells act as statoliths, which are involved in gravity perception. When a root is placed on its side, the amyloplasts settle in the direction of gravity, helping the plant to sense and respond to the change in orientation.
