Question

what is the main function of the chloroplast in a plant cell?
to produce steroid hormones

to fill the space between the cell membrane and the nucleus

to use energy from sunlight to make sugar

to give structure and organization to the cell

Explanation:

• Chloroplasts in plant cells are the site of photosynthesis. Photosynthesis uses sunlight energy to convert carbon dioxide and water into glucose (sugar) and oxygen.
• "To produce steroid hormones" is incorrect as chloroplasts don't produce steroid hormones (that's more related to certain organelles in animal cells or other plant structures).
• "To fill the space between the cell membrane and the nucleus" describes cytoplasm, not chloroplasts.
• "To give structure and organization to the cell" is a function of the cytoskeleton or cell wall, not chloroplasts.

Answer:

to use energy from sunlight to make sugar
