The vegetative part of the male gametophyte of Selaginella is represented by

Options

A. Prothallial cell
B. Androgonial cells
C. Jacket cells
D. All the obove structures.

Answer

To solve the question regarding the vegetative part of the male gametophyte of Selaginella, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Organism**:
- Selaginella is a type of pteridophyte, commonly referred to as a fern. It is important to note that it is a seedless plant.

2. **Identify Male and Female Spores**:
- In Selaginella, male spores are produced in structures called microsporangia. The term "micro" indicates that these spores are small and specifically refer to male gametes.

3. **Definition of Gametophyte**:
- The gametophyte is the haploid phase of the plant life cycle responsible for the production of gametes (sperm and eggs). In Selaginella, the male gametophyte is also haploid.

4. **Identify the Vegetative Structure**:
- The vegetative part of the male gametophyte in Selaginella is known as the prothallus. The cells that make up this prothallus are referred to as prothelial cells.

5. **Evaluate the Options**:
- Option 1: Prothelial cell - This is correct as it represents the vegetative part of the male gametophyte.
- Option 2: Androgonial cell - This is incorrect as it does not represent the vegetative structure.
- Option 3: Jacket cell - This is also incorrect as it relates to female gametes.
- Option 4: All of the above - This is incorrect as not all options are correct.

6. **Conclusion**:
- The correct answer is option 1: Prothelial cell.

### Final Answer:
The vegetative part of the male gametophyte of Selaginella is represented by **prothelial cell**.
