Final answer:
The chloroplast is the site of photosynthesis in plants, algae, and some bacteria.
Step-by-step explanation:
The function of the chloroplast is to be the site of photosynthesis. Photosynthesis is the process by which plants, algae, and some bacteria convert sunlight, carbon dioxide, and water into glucose and oxygen. It occurs in specialized structures called chloroplasts, which contain the pigment chlorophyll. Chlorophyll absorbs light energy and uses it to synthesize glucose, providing the energy needed for plant growth and survival.
