Biology

The correct answer is A. chloroplast.

Photosynthesis, the process by which plants, algae, and some bacteria convert light energy into chemical energy, occurs primarily in the chloroplasts. Chloroplasts are specialized organelles found in plant cells and some other organisms capable of photosynthesis. They contain chlorophyll, the pigment responsible for capturing light energy. Within the chloroplasts, the light-dependent reactions and the light-independent reactions (also known as the Calvin cycle) take place, enabling the conversion of sunlight into glucose and oxygen.
