In chloroplasts the chlorophyll is located in

Options

A. Grana
B. Pyrenoid
C. Stroma
D. Both grana and stroma

Answer

**Step-by-Step Solution:**

1. **Understanding Chloroplast Structure**: Chloroplasts are the organelles in plant cells where photosynthesis occurs. They are made up of two main components: thylakoids and stroma.

2. **Identifying Thylakoids**: Thylakoids are internal membrane structures within the chloroplast that are organized into stacks. These stacks are known as grana (singular: granum).

3. **Location of Chlorophyll**: Chlorophyll, the pigment responsible for capturing light energy, is located in the thylakoid membranes. Therefore, it is primarily found in the grana, which are composed of these thylakoid stacks.

4. **Function of Grana**: The grana are specifically the sites where the light-dependent reactions of photosynthesis occur, making them crucial for the process of converting light energy into chemical energy.

5. **Conclusion**: Since chlorophyll is located in the thylakoids that make up the grana, the correct answer to the question is that chlorophyll is located in the grana of the chloroplasts.

**Final Answer**: Grana
