Heterosporous pteridophytes produce

Options

A. dioecious gametophytes
B. monoecious gametophytes
C. homothallic gametophytes
D. hermaphrodite gametophytes

Answer

### Step-by-Step Solution:

1. **Understanding Heterosporous Pteridophytes**:
- Heterosporous pteridophytes are a group of plants that produce two distinct types of spores: megaspores and microspores.

2. **Identifying the Types of Spores**:
- **Megaspores**: These are larger spores that develop into female gametophytes (megagametophytes).
- **Microspores**: These are smaller spores that develop into male gametophytes (microgametophytes) and produce sperm.

3. **Understanding Gametophyte Types**:
- The gametophytes produced from these spores can be classified based on their sexual characteristics:
- **Dioecious**: Male and female gametophytes are produced on separate plants.
- **Monoecious**: Both male and female gametophytes are produced on the same plant.
- **Homothallic**: Refers to gametophytes that can produce both male and female gametes.
- **Hermaphrodite**: Similar to homothallic, where a single gametophyte produces both types of gametes.

4. **Conclusion**:
- Since heterosporous pteridophytes produce two types of gametophytes (male and female) from their respective spores, they are classified as dioecious gametophytes.

5. **Final Answer**:
- Heterosporous pteridophytes produce dioecious gametophytes.
