In moss , sporophyte is formed on

Options

A. antheridia.
B. archegonia.
C. prothallus.
D. leafy stage.

Answer

To answer the question "In moss, sporophyte is formed on," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Life Cycle of Moss:**
- Mosses are classified as bryophytes, which are known for having a dominant gametophyte stage in their life cycle. The sporophyte stage is dependent on the gametophyte.

2. **Identify the Structures Involved:**
- In mosses, the gametophyte produces two types of sex organs: antheridia (male) and archegonia (female). The sporophyte develops from the zygote formed after fertilization of gametes produced by these sex organs.

3. **Determine Where the Sporophyte Forms:**
- The sporophyte in mosses is not formed on the antheridia or archegonia directly. Instead, it develops from the zygote that is retained within the archegonium after fertilization.

4. **Consider the Leafy Stage:**
- The leafy stage of moss is the mature gametophyte that bears the sex organs. The sporophyte grows out of the archegonium, which is part of the leafy stage.

5. **Conclusion:**
- Therefore, the correct answer to the question is that the sporophyte is formed on the leafy stage of the moss.

### Final Answer:
The sporophyte in moss is formed on the **leafy stage**.
