In the plant cell, the site of starch synthesis and storage is the

A. Chloroplast and amyloplast
✓
B. Smooth endoplasmic reticulum
C. Golgi apparatus
D. Mitochondrial matrix

📝 Explanation

Starch is synthesized in plastids. Transitory starch is synthesized in chloroplasts during photosynthesis and broken down at night. Storage starch is synthesized and stored in amyloplasts (non-pigmented plastids) in tissues like tubers, seeds, and roots.
