Most advanced group of Algae is :-

Options

A. Myxophyta
B. Chlorophyta
C. Rhodophyta
D. Phaeophyta

Answer

**Step-by-Step Solution:**

1. **Identify the Options**: The question provides four options: Myxophyta, Chlorophyta, Rhodophyta, and Pheophyta.

2. **Evaluate Myxophyta**: Myxophyta is not a class of algae; it refers to cyanobacteria. Therefore, this option is incorrect.

3. **Compare the Remaining Classes**: We need to compare Chlorophyta (green algae), Rhodophyta (red algae), and Pheophyta (brown algae) based on certain characteristics.

4. **Examine Pigments**:
- **Chlorophyta**: Contains chlorophyll (green pigment).
- **Rhodophyta**: Contains phycoerythrin (red pigment).
- **Pheophyta**: Contains fucoxanthin (brown pigment).

5. **Determine Color**:
- **Chlorophyta**: Green.
- **Rhodophyta**: Red.
- **Pheophyta**: Brown.

6. **Analyze Cell Wall Composition**:
- All three classes (Chlorophyta, Rhodophyta, and Pheophyta) have cell walls made of cellulose.

7. **Evaluate Food Storage**:
- **Chlorophyta**: Stores food as starch.
- **Rhodophyta**: Stores food as Floridian starch.
- **Pheophyta**: Stores food as Laminarin and Mannitol.

8. **Storage Bodies**:
- Chlorophyta has specialized bodies called "paranoid bodies" for starch storage, while Rhodophyta and Pheophyta do not have specific storage bodies.

9. **Conclusion**: Based on the comparison of pigments, food storage, and specialized storage bodies, Chlorophyta (green algae) is considered the most advanced group of algae.

10. **Final Answer**: The most advanced group of algae is **Chlorophyta** (option 2).
