Question

what is the main function of the chloroplast in a plant cell?
to store waste in the cell
to direct cell activities by sending instructions to different parts of the cell
to use energy from sunlight to make sugar
to make proteins

Explanation:

Chloroplasts contain chlorophyll. Chlorophyll captures sunlight. Through photosynthesis (which occurs in chloroplasts), plants convert sunlight, carbon dioxide, and water into sugar (glucose) and oxygen. Storing waste is a function of vacuoles. Directing cell activities is the role of the nucleus. Making proteins is mainly done by ribosomes. So the main function of chloroplasts is using sunlight energy to make sugar.

Answer:

to use energy from sunlight to make sugar
