Pigment present in some Slime Moulds is

Options

A. Chlorophyll
B. Carotenoids
C. Anthracene
D. Both B and C.

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the pigment present in some slime moulds. It provides multiple options: chlorophyll, carotenoid, anthracene, and both B and C.

2. **Identifying the Characteristics of Slime Moulds**: Slime moulds are part of the kingdom Protista and are primarily known for their role as decomposers in the ecosystem. They do not perform photosynthesis like plants.

3. **Analyzing the Options**:
- **Chlorophyll**: This pigment is found in plants and is essential for photosynthesis. Since slime moulds do not perform photosynthesis, they do not have chlorophyll.
- **Carotenoid**: This pigment is also associated with photosynthesis and is found in many plants. Similar to chlorophyll, slime moulds do not possess carotenoids.
- **Anthracene**: This is a pigment that can be found in some slime moulds, particularly in acellular slime moulds. It imparts a yellow color to these organisms.

4. **Conclusion**: Since slime moulds do not have chlorophyll or carotenoids, the only pigment that fits the criteria is anthracene. Therefore, the correct answer to the question is anthracene.

5. **Final Answer**: The pigment present in some slime moulds is **anthracene**.
