In mosses the sex organs are present in the

Options

A. Protonema stage
B. Sporophytic stage
C. Leafy stage
D. Both (1) & (2)

Answer

**Step-by-Step Solution:**

1. **Understanding Mosses**: Mosses are classified as bryophytes, which are non-vascular plants. They have a more complex life cycle compared to liverworts.

2. **Life Cycle of Mosses**: The life cycle of mosses includes several stages:
- **Spores**: The life cycle begins with the production of spores.
- **Protonema Stage**: The spores germinate to form a juvenile structure called the protonema.
- **Leafy Stage**: The protonema develops into a leafy gametophyte stage.

3. **Sex Organs Location**: In mosses, the sex organs (antheridia for male and archegonia for female) are located on the gametophyte, specifically on the leafy stage.

4. **Sporophyte Stage**: The sporophyte, which develops from the fertilized egg, is dependent on the gametophyte for nutrition and does not bear sex organs.

5. **Conclusion**: Therefore, in mosses, the sex organs are present in the leafy stage of the gametophyte.

**Final Answer**: The sex organs in mosses are present in the leafy stage of the gametophyte.
