A naked sporangium occurs in

Options

A. Cellular slime moulds
B. Acellular slime moulds
C. All the slime moulds
D. Commonly acellular slime moulds but at times cellular slime moulds,

Answer

To answer the question "A naked sporangium occurs in," we will follow these steps:

### Step-by-Step Solution:

1. **Understanding Sporangium**:
- A sporangium is a structure that produces and contains spores. It is commonly found in fungi and certain protists, including slime molds.

2. **Identifying Types of Slime Molds**:
- There are two main types of slime molds: cellular slime molds and acellular slime molds (also known as plasmodial slime molds).

3. **Characteristics of Cellular Slime Molds**:
- In cellular slime molds, the sporangium is described as "naked," meaning it does not have a protective covering or wall around it. The spores produced are surrounded by cellulose walls.

4. **Characteristics of Acellular Slime Molds**:
- In contrast, acellular slime molds have a sporangium that is not naked; it is covered by a wall. This is a key distinguishing feature.

5. **Conclusion**:
- Based on the characteristics of both types of slime molds, we conclude that a naked sporangium occurs specifically in cellular slime molds.

### Final Answer:
A naked sporangium occurs in **cellular slime molds**.
