Where does photosynthesis primarily occur in plant cells?

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

Answer: (C)

Verified step by step guidance

1. Understand that photosynthesis is the process by which plants convert light energy into chemical energy stored in glucose.
2. Recall that photosynthesis requires specific organelles that contain pigments like chlorophyll to capture light energy.
3. Identify the organelle in plant cells that contains chlorophyll and is specialized for photosynthesis; this organelle is the chloroplast.
4. Recognize that mitochondria are involved in cellular respiration, ribosomes in protein synthesis, and the nucleus in genetic information storage, so they are not the primary sites of photosynthesis.
5. Conclude that photosynthesis primarily occurs in the chloroplasts of plant cells.
