Answer:
[A] Cell Wall
[B] ER
[D] Chloroplast
Explanation:
The cell wall is a rigid covering that protects the cell, provides structural support, and gives shape to the plant cell.
The ER is the production, processing, and transport of proteins and lipids.
Chloroplasts enable the conversion of light energy into the chemical form without which the plants would be unable to perform photosynthesis.
