Flagellated cells are absent in :-

Options

A. Red algae
B. Blue green algae
C. Higher seed plants
D. All of the above

Answer

To solve the question "Flagellated cells are absent in:", we will analyze each option provided.

### Step-by-Step Solution:

1. **Understanding Flagellated Cells**:
- Flagellated cells are cells that possess flagella, which are whip-like structures used for movement. We need to identify which of the given options lack these cells.

2. **Analyzing Red Algae**:
- Red algae (Rhodophyta) are eukaryotic organisms. They are known to lack flagella in their life cycle. Therefore, they do not have flagellated cells.

3. **Analyzing Blue Green Algae**:
- Blue green algae, also known as cyanobacteria, are prokaryotic organisms. They do not have flagella. Instead, they exhibit gliding movement through slime secretion. Thus, they also lack flagellated cells.

4. **Analyzing Higher Seed Plants**:
- Higher seed plants, which include gymnosperms and angiosperms, do not have flagellated cells. The presence of pollen grains in these plants has eliminated the need for water for fertilization, which means flagella are not present.

5. **Conclusion**:
- Since all the options (red algae, blue green algae, and higher seed plants) lack flagellated cells, the correct answer is "all of the above".

### Final Answer:
- **Flagellated cells are absent in: All of the above (Red algae, Blue green algae, Higher seed plants)**.
