Photosynthetic pigments of bacteria are located in

Options

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

Answer

To answer the question regarding the location of photosynthetic pigments in bacteria, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Classification of Bacteria**:
- Bacteria belong to the kingdom Monera, which consists of prokaryotic organisms. Prokaryotes are characterized by the absence of membrane-bound organelles.

2. **Identify Membrane-Bound Organelles**:
- In higher plants, photosynthetic pigments are found in organelles called plastids, which include chloroplasts, chromoplasts, and leukoplasts. However, since bacteria do not have these membrane-bound organelles, we need to look for alternatives.

3. **Focus on Photosynthetic Bacteria**:
- Some bacteria are photosynthetic, such as cyanobacteria and purple sulfur bacteria. These bacteria have developed structures that allow them to perform photosynthesis.

4. **Learn About Thylakoids**:
- In photosynthetic bacteria, the photosynthetic pigments are located in structures called thylakoids. Thylakoids are membrane-lined sacs that are derived from the plasma membrane of the bacteria.

5. **Identify the Photosynthetic Pigments**:
- The main photosynthetic pigments found in these thylakoids include bacteriochlorophyll, bacteriophyophytin, and carotenoids.

6. **Conclusion**:
- Therefore, the correct answer to the question is that the photosynthetic pigments of bacteria are located in the **thylakoids**.

### Final Answer:
The photosynthetic pigments of bacteria are located in the **thylakoids**.
