Pyrenoid contains -

Options

A. Polysaccharide + Lipid
B. Starch + Lipid
C. Protein + Starch
D. Starch + Glycogen

Answer

**Step-by-Step Solution:**

1. **Understanding Pyrenoids**:
- Pyrenoids are specialized structures found within the chloroplasts of certain algae. They are involved in the storage of carbohydrates.

2. **Identifying the Components of Pyrenoids**:
- Pyrenoids primarily contain starch, which is a polysaccharide, and proteins.

3. **Analyzing the Options**:
- The question provides four options:
- A) Polysaccharide plus Lipid
- B) Starch plus Lipid
- C) Protein plus Starch
- D) Starch plus Glycogen

4. **Eliminating Incorrect Options**:
- Option A (Polysaccharide plus Lipid) does not include protein, which is a key component of pyrenoids.
- Option B (Starch plus Lipid) also lacks protein.
- Option D (Starch plus Glycogen) includes glycogen, which is not a primary component of pyrenoids.

5. **Selecting the Correct Answer**:
- The only option that includes both starch and protein is option C (Protein plus Starch).

6. **Conclusion**:
- Therefore, the correct answer is that pyrenoids contain **Protein plus Starch**.

**Final Answer**: Pyrenoid contains **Protein plus Starch**.
