In some photosynthetic prokaryotes pigments containing structure is

Options

A. Chloroplast
B. Chromatophore
C. Chromoplast
D. Capsule

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the structure in some photosynthetic prokaryotes that contains pigments. We need to identify which of the given options is correct.

2. **Analyzing the Options**:
- **Chloroplast**: This structure is known to be present in eukaryotic cells, specifically in plants and algae. It is responsible for photosynthesis but is not found in prokaryotes. Therefore, this option is incorrect.

- **Chromatophores**: These are pigment-containing structures found in some prokaryotic organisms, particularly in certain bacteria. They are essential for photosynthesis in these organisms as they contain pigments like carotenoids. This option is likely correct.

- **Chromoplast**: This is a type of plastid that contains pigments other than chlorophyll, such as carotenoids, and is found in eukaryotic cells. It is not associated with prokaryotes, making this option incorrect.

- **Capsule**: The capsule is a protective layer found outside the cell wall in some bacteria. It does not contain pigments and is not involved in photosynthesis, so this option is also incorrect.

3. **Conclusion**: Based on the analysis, the correct answer is **chromatophores**, as they are the pigment-containing structures found in photosynthetic prokaryotes.

**Final Answer**: Chromatophores
