Hi there

Please find the answer below:

Chloroplasts are the cell organelles (Cell organs, in simple terms) in plant cells.

The primary function of chloroplasts is to carry out photosynthesis which is a process of capturing light energy and converting it into chemical energy.

And using that energy to synthesize organic molecules (such as glucose) from carbon dioxide and water.
