Reserve food of algae and fungi are :-

Options

A. Starch and soluble floridoside
B. Oil droplets and fats
C. Starch and glycogen
D. Starch and Glycerol

Answer

To determine the reserve food of algae and fungi, we can analyze each option provided in the question step by step.

### Step-by-Step Solution:

1. **Understanding Algae and Fungi:**
- Algae are primarily photosynthetic organisms that can store energy in the form of carbohydrates.
- Fungi are heterotrophic organisms that obtain their nutrients from organic matter and store energy in different forms.

2. **Analyzing the Options:**
- **Option 1: Starch and Soluble Floridoside**
- Starch is indeed a reserve food in algae, but soluble floridoside is not a reserve food; it is a photosynthetic product found in red algae. Therefore, this option is incorrect.

- **Option 2: Oil Droplets and Fats**
- Oil droplets and fats are not the primary reserve foods for algae. While fungi can store energy in the form of fats, this option does not correctly represent the reserve foods for both groups. Hence, this option is also incorrect.

- **Option 3: Starch and Glycogen**
- This option is correct. Starch is the reserve food in algae, while glycogen serves as the reserve food in fungi. This option accurately describes the reserve foods for both organisms.

- **Option 4: Starch and Glycerol**
- Starch is a reserve food for algae, but glycerol is not a primary reserve food for fungi. Glycogen is the correct reserve food for fungi. Therefore, this option is incorrect.

3. **Conclusion:**
- The correct answer is **Starch and Glycogen** as they are the reserve foods of algae and fungi, respectively.

### Final Answer:
The reserve food of algae is starch, and the reserve food of fungi is glycogen.
