In plant cells, photosynthesis primarily occurs in which organelle?

• A. Golgi apparatus
• B. Chloroplast
• C. Rough endoplasmic reticulum
• D. Mitochondrion

Answer: (B)

Verified step by step guidance

1. Identify the organelle responsible for photosynthesis in plant cells by recalling the function of each listed organelle.
2. Recall that the Golgi apparatus is involved in modifying, sorting, and packaging proteins and lipids, not photosynthesis.
3. Understand that the rough endoplasmic reticulum is primarily involved in protein synthesis due to the presence of ribosomes on its surface.
4. Recognize that mitochondria are the site of cellular respiration, producing ATP by breaking down glucose, but do not perform photosynthesis.
5. Know that chloroplasts contain chlorophyll and are the organelles where photosynthesis takes place, converting light energy into chemical energy.
