Photosynthetic pigments are located in the chloroplast in

Options

A. Intrathylakoid space
B. Thylakoid membranes
C. Intermembrane space
D. Inner membrane of envelope

Answer

**Step-by-Step Solution:**

1. **Understanding the Structure of Chloroplasts:**
- Chloroplasts are double-membrane-bound organelles found in plant cells and some algae. They are the site of photosynthesis.

2. **Identifying the Components of Chloroplasts:**
- Chloroplasts contain an inner and outer membrane, and within them is a complex system of membranes known as thylakoids.

3. **Location of Photosynthetic Pigments:**
- The photosynthetic pigments, primarily chlorophyll, are located in the thylakoid membranes. These membranes are arranged in stacks called grana.

4. **Other Spaces in the Chloroplast:**
- The stroma is the fluid-filled space surrounding the thylakoids, but it does not contain the photosynthetic pigments. The intermembrane space is the area between the inner and outer membranes, and the inner membrane of the envelope does not contain the pigments either.

5. **Conclusion:**
- Based on this information, the correct answer to the question "Photosynthetic pigments are located in the chloroplast in" is the **thylakoid membranes**.

**Final Answer:**
- Photosynthetic pigments are located in the chloroplast in **thylakoid membranes**.
