Photosynthetic bacteria have pigments in

Options

A. Chromatophores
B. leucoplast
C. Chromoplast
D. Chloroplast

Answer

To solve the question regarding where photosynthetic bacteria have their pigments, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Options**: The question provides four options: Leucoplasm, Chromoplasm, Chloroplasm, and Chromatophore. We need to determine which of these contains pigments in photosynthetic bacteria.

2. **Identifying Chromatophores**: From the video transcript, it is stated that chromatophores are present in all photosynthetic bacteria. This indicates that chromatophores are specialized structures that contain pigments.

3. **Types of Pigments in Chromatophores**: The transcript mentions that chromatophores contain several types of pigments, including beta carotene, xanthophyll, phycoerythrin, and phycocyanin. These pigments are essential for the process of photosynthesis as they help in absorbing light.

4. **Function of Chromatophores**: Chromatophores are described as pigment-containing and light-reflecting cells. They are responsible for absorbing light at specific wavelengths (460 to 550 nm), which is crucial for photosynthesis.

5. **Conclusion**: Based on the information provided, the correct answer to the question "Photosynthetic bacteria have pigments in" is **Chromatophore**.

### Final Answer:
**Chromatophore**
