In homosporous pteridophyte the gametophyte is -

Options

A. Vascular
B. Monoecious
C. Dioecious
D. Dependent on sporophyte

Answer

To answer the question "In homosporous pteridophyte the gametophyte is -", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Homosporous Pteridophytes**:
- Homosporous pteridophytes are plants that produce only one type of spore, which develops into a gametophyte. Examples include ferns and horsetails.

2. **Definition of Gametophyte**:
- The gametophyte is the stage in the plant life cycle that produces gametes (sperm and eggs). In pteridophytes, the gametophyte is often referred to as prothallus.

3. **Characteristics of the Gametophyte in Homosporous Pteridophytes**:
- The gametophyte (prothallus) is typically:
- **Non-vascular**: It does not have vascular tissues like xylem and phloem.
- **Freeliving**: It can exist independently of the sporophyte.
- **Photosynthetic**: It can perform photosynthesis to produce its own food.
- **Thalloid**: It has a flat, thallus-like structure.

4. **Sexual Reproductive Structures**:
- The gametophyte produces both male and female reproductive organs:
- **Antheridia**: The male reproductive organ.
- **Archegonia**: The female reproductive organ.
- Since both types of reproductive organs are present on the same gametophyte, this condition is referred to as **monaceous**.

5. **Conclusion**:
- Based on the characteristics discussed, the correct answer to the question is that in homosporous pteridophytes, the gametophyte is **monaceous**.

### Final Answer:
In homosporous pteridophyte, the gametophyte is **monaceous**.
