Which organelle is primarily involved in photosynthesis?

• A. Chloroplast
• B. Mitochondria
• C. Ribosome
• D. Endoplasmic reticulum

Answer: (A)

The chloroplast is primarily involved in photosynthesis, the process by which plants, algae, and some bacteria convert light energy into chemical energy stored in glucose. Chloroplasts contain chlorophyll, the green pigment that captures light energy, and a variety of enzymes that facilitate the complex series of reactions necessary for converting carbon dioxide and water into glucose and oxygen, using sunlight as the energy source. The structure of chloroplasts, which includes thylakoid membranes where light-dependent reactions occur and the stroma where the Calvin cycle takes place, is specifically adapted for these processes, making them the key organelles responsible for photosynthesis in plant cells.
