Glycogen is the reserve food in
I) Rhizopus II ) funaria
III ) Bacteria IV ) Spirogyra

Options

A. I and III
B. II and IV
C. I and II
D. III and IV

Answer

To solve the question regarding which organisms have glycogen as their reserve food material, we will analyze each option provided:

1. **Rhizopus**:
- Rhizopus is a genus of fungi. In fungi, glycogen is commonly used as a storage polysaccharide, similar to how animals use it. Therefore, Rhizopus does indeed store energy in the form of glycogen.

2. **Funaria**:
- Funaria is a genus of mosses, which are bryophytes. Bryophytes typically store their energy in the form of starch, not glycogen. Thus, Funaria does not use glycogen as its reserve food.

3. **Bacteria**:
- Many bacteria also store energy in the form of glycogen. It serves as a reserve food material for various bacterial species, allowing them to utilize it when needed.

4. **Spirogyra**:
- Spirogyra is a green algae, and like many other algae, it primarily stores energy in the form of starch rather than glycogen. Therefore, Spirogyra does not utilize glycogen as its reserve food.

Now, summarizing the findings:
- **Rhizopus**: Glycogen (Yes)
- **Funaria**: Starch (No)
- **Bacteria**: Glycogen (Yes)
- **Spirogyra**: Starch (No)

Based on this analysis, the organisms that use glycogen as their reserve food material are **Rhizopus** and **Bacteria**.

Thus, the correct answer to the question is **I) Rhizopus and III) Bacteria**.

### Final Answer:
Glycogen is the reserve food in **I) Rhizopus and III) Bacteria**.
