In Selaginella, the megasporophyll is comparable to a structure in angiosperms

Options

A. Stamen
B. Leaf
C. Carpel
D. Ovule.

Answer

To answer the question regarding the comparison of the megasporophyll in Selaginella to a structure in angiosperms, we can break down the solution into the following steps:

### Step-by-Step Solution:

1. **Identify the Organism**:
- Selaginella is a genus that belongs to the group Pteridophyta, which includes ferns and their relatives.

2. **Understand the Structure**:
- The megasporophyll is a leaf-like structure that bears megaspores. In Selaginella, this structure is involved in the reproductive process.

3. **Locate the Equivalent Structure in Angiosperms**:
- In angiosperms (flowering plants), the equivalent structure that contains the ovules (which develop into seeds) is known as the carpel.

4. **Function of the Structures**:
- The megasporophyll in Selaginella is responsible for producing megaspores, similar to how the carpel in angiosperms houses ovules and is involved in the female reproductive process.

5. **Conclusion**:
- Therefore, the megasporophyll in Selaginella is comparable to the carpel in angiosperms, as both structures are involved in the reproduction of the plant and represent the female reproductive parts.

### Final Answer:
The megasporophyll in Selaginella is comparable to the carpel in angiosperms.
