Pyrenoids are characteristically found in the chloroplast of

Options

A. Angiosperms
B. Pteridophytes
C. Algae
D. Fungi.

Answer

**Step-by-Step Solution:**

1. **Understanding Pyrenoids**: Pyrenoids are specialized structures found within the chloroplasts of certain algae and are involved in the storage of starch and proteins.

2. **Identifying the Organisms**: The question provides four options: angiosperms, pteridophytes, algae, and fungi. We need to determine which of these groups characteristically contains pyrenoids.

3. **Analyzing the Options**:
- **Angiosperms**: These are flowering plants and do not typically contain pyrenoids.
- **Pteridophytes**: These are vascular plants like ferns and also do not have pyrenoids.
- **Algae**: This group includes various types of photosynthetic organisms, many of which contain pyrenoids, especially within the green algae (Chlorophyceae).
- **Fungi**: These are non-photosynthetic organisms and do not possess chloroplasts or pyrenoids.

4. **Conclusion**: Based on the analysis, pyrenoids are characteristically found in the chloroplasts of algae, particularly in the green algae.

5. **Final Answer**: Therefore, the correct answer is **C) Algae**.
