Photosynthetic bacteria have pigments in

Options

A. chromatophores
B. leucoplast
C. chromoplast
D. chloroplast

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks where photosynthetic bacteria contain their pigments. We need to identify the correct structure associated with photosynthesis in bacteria.

2. **Analyzing the Options**:
- **Option A: Chromatophores**: These are membrane-bound structures in photosynthetic bacteria that contain pigments.
- **Option B: Leukoplast**: These are non-pigmented plastids found in plant cells, primarily involved in storage.
- **Option C: Chromoplast**: These are colored plastids in plants that contain pigments but are not found in bacteria.
- **Option D: Chloroplast**: These are the organelles in plant cells responsible for photosynthesis, but they are not present in bacteria.

3. **Identifying the Correct Answer**: Since photosynthetic bacteria utilize chromatophores to house their photosynthetic pigments, the correct answer is **Option A: Chromatophores**.

4. **Explanation of Chromatophores**: Chromatophores are extensions of the cytoplasmic membrane in bacteria and contain photosynthetic pigments such as bacteriochlorophyll and bacteriopheophytin, which are essential for the process of photosynthesis.

5. **Final Answer**: Therefore, the correct answer to the question is **Chromatophores**.
