Question

Which cell organelle in a plant cell participates in photosynthesis

• A. Mitochondria
• B. Chloroplast
• C. Golgi complex
• D. Endoplasmic reticulum

Answer 1

The Correct Option is B

To solve the problem, we need to identify the cell organelle in a plant cell that participates in photosynthesis.

1. Understanding Photosynthesis:
Photosynthesis is the process by which plants convert light energy into chemical energy, using carbon dioxide and water to produce glucose and oxygen. This process occurs in plant cells in a specific organelle.

2. Evaluating the Options:
- Option (A): Mitochondria – Mitochondria are involved in cellular respiration, not in photosynthesis.
- Option (B): Chloroplast – Chloroplasts contain chlorophyll, which absorbs light energy and is the site of photosynthesis.
- Option (C): Golgi complex – The Golgi apparatus is involved in processing and packaging proteins, not in photosynthesis.
- Option (D): Endoplasmic reticulum – The ER is involved in protein synthesis and transport, not in photosynthesis.

3. Conclusion:
The cell organelle responsible for photosynthesis in plant cells is the chloroplast.

Final Answer:
The correct answer is option (B): Chloroplast.
