Pyrenoids store food as

Options

A. Glycogen
B. Fats
C. Oil globules
D. Starch.

Answer

To answer the question "Pyrenoids store food as:", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Pyrenoids**:
- Pyrenoids are specialized structures found within the chloroplasts of certain algae, particularly in the group known as chlorophyceae (green algae).
- They are involved in the storage of food materials.

2. **Identifying Food Storage Forms**:
- Pyrenoids can store various types of food substances. The options provided are:
- A) Glycogen
- B) Fats (oil globules)
- C) Starch

3. **Analyzing Each Option**:
- **Glycogen**: While glycogen is a storage form of glucose in animals, it is not typically associated with pyrenoids in green algae.
- **Fats (oil globules)**: Some algae do store energy in the form of oil droplets, but this is not the primary function of pyrenoids.
- **Starch**: Pyrenoids are known to primarily store starch, which is a polysaccharide that serves as an energy reserve.

4. **Conclusion**:
- Based on the analysis, the primary storage form associated with pyrenoids is starch. Therefore, the correct answer is:
- **D) Starch**

### Final Answer:
**D) Starch**
