Which are the pigments found in phaeophyceae?

Answer

### Step-by-Step Solution:

1. **Introduction to Phaeophyceae**:
- Phaeophyceae, commonly known as brown algae, are a group of multicellular marine algae. They are primarily found in marine environments.

2. **Pigments in Phaeophyceae**:
- The dominant pigments in Phaeophyceae are responsible for their characteristic brown color. The main pigments include:
- **Fucosanthin**: This pigment contributes to the brownish color of the algae.
- **Chlorophyll a**: This pigment is involved in photosynthesis and gives a greenish hue.
- **Chlorophyll c**: Similar to chlorophyll a, this pigment also aids in photosynthesis and contributes to the coloration of the algae.
- **Xanthophyll**: This pigment is a type of carotenoid that gives a yellowish-brown color and is also present in these algae.

3. **Conclusion**:
- In summary, the pigments found in Phaeophyceae (brown algae) are fucosanthin, chlorophyll a, chlorophyll c, and xanthophyll. These pigments play a crucial role in photosynthesis and contribute to the overall coloration of the algae.
