When the gametophyte development occurs within spore, it is known as

Options

A. Exosporic
B. Endosporic
C. Episporic
D. None of these

Answer

To answer the question "When the gametophyte development occurs within spore, it is known as," we will follow these steps:

### Step-by-Step Solution:

1. **Understanding the Terms**:
- First, we need to understand what a gametophyte is. The gametophyte is the haploid phase in the life cycle of plants, which is involved in the production of gametes (sperm and eggs).
- A spore is a reproductive unit that can develop into a new organism without the need for fertilization.

2. **Identifying the Context**:
- The question refers to the development of the gametophyte occurring within a spore. This is a specific developmental process that can be observed in certain plant groups.

3. **Analyzing the Options**:
- The options provided are:
- Exosporic
- Endosporic
- Episporic
- None of these
- We need to determine which term correctly describes the development of the gametophyte inside the spore.

4. **Defining the Terms**:
- **Exosporic**: This term refers to development occurring outside the spore.
- **Endosporic**: This term means development occurring inside the spore.
- **Episporic**: This term is not commonly used in this context and does not apply here.
- **None of these**: This option would only be correct if none of the other terms fit.

5. **Conclusion**:
- Since the question specifically asks about the development of the gametophyte occurring within the spore, the correct term is **endosporic**. The prefix "endo-" means "inside," which aligns with the definition provided.

### Final Answer:
When the gametophyte development occurs within the spore, it is known as **endosporic**.
