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.
