Question

what function do chloroplasts perform?
they use light energy to make food for the plant.
they control the activities in the cell.
they produce proteins for the cell.
they provide temporary storage for the plants water.

Explanation:

Chloroplasts contain chlorophyll which captures light energy. Through photosynthesis (a process in chloroplasts), plants convert carbon dioxide and water into glucose (food for the plant) using light energy. The nucleus controls cell activities, ribosomes produce proteins, and vacuoles (in plants, large central vacuole) can store water.

Answer:

They use light energy to make food for the plant.
