Where does photosynthesis primarily take place in plant cells?

• A. Ribosomes
• B. Nucleus
• C. Mitochondria
• D. Chloroplasts

Answer: (D)

Verified step by step guidance

1. Photosynthesis is the process by which plants convert light energy into chemical energy stored in glucose molecules. To understand where this process occurs, we need to identify the organelle responsible for capturing light energy.
2. In plant cells, chloroplasts are specialized organelles that contain chlorophyll, a pigment that absorbs light energy. Chloroplasts are the primary site of photosynthesis.
3. Ribosomes are responsible for protein synthesis, not photosynthesis. They are unrelated to the process of converting light energy into glucose.
4. The nucleus is the control center of the cell, housing genetic material, but it does not play a direct role in photosynthesis.
5. Mitochondria are involved in cellular respiration, where glucose is broken down to produce ATP, but they do not perform photosynthesis. Therefore, the correct answer is chloroplasts.
