Options

A. Starch
B. Glycogen
C. Sugar
D. Fat

Answer

### Step-by-Step Solution:

1. **Understanding Green Algae**:
- Green algae belong to the group known as Chlorophyceae. They are characterized by their high chlorophyll content, which gives them their green color.

2. **Types of Chlorophyll**:
- Green algae contain two main types of chlorophyll: chlorophyll A and chlorophyll B. These pigments are crucial for photosynthesis, allowing the algae to convert sunlight into energy.

3. **Photosynthesis and Food Production**:
- Through the process of photosynthesis, green algae produce various organic compounds, primarily carbohydrates.

4. **Reserve Food Material**:
- The primary reserve food material produced by green algae is starch. This starch is synthesized during photosynthesis and serves as an energy reserve.

5. **Storage of Starch**:
- The starch produced in green algae is stored in specialized organelles called plastids. This storage mechanism is essential for the algae to utilize the energy when needed.

6. **Conclusion**:
- Based on the above points, the correct answer to the question "Reserve food material of green algae is?" is **starch**.

### Final Answer:
The reserve food material of green algae is **starch**.
