Chlorophyll occurs in chloroplast

Options

A. inner membrane
B. thylakoid membrane
C. outer membrane
D. stroma

Answer

**Step-by-Step Solution:**

1. **Understanding the Structure of Chloroplasts:**
- Chloroplasts are membrane-bound organelles found in plant cells and some algae. They have a unique structure consisting of three membranes: an outer membrane, an inner membrane, and the thylakoid membrane.

2. **Identifying the Membranes:**
- The outer membrane is the first layer that surrounds the chloroplast.
- The inner membrane lies just inside the outer membrane.
- The thylakoid membrane is the third membrane, which is folded into structures called thylakoids.

3. **Function of the Thylakoid Membrane:**
- The thylakoid membrane is crucial for photosynthesis. It contains chlorophyll, which is the pigment responsible for capturing light energy.

4. **Location of Chlorophyll:**
- Chlorophyll is specifically located in the thylakoid membrane. This is where it plays its role in converting light energy into chemical energy during the process of photosynthesis.

5. **Conclusion:**
- Therefore, the correct answer to the question "Chlorophyll occurs in chloroplast" is that chlorophyll is found in the thylakoid membrane.

**Final Answer:**
Chlorophyll occurs in the thylakoid membrane of the chloroplast.
