Leafy gametophyte occurs in:-

Options

A. Liver worts
B. Horn worts
C. Moss
D. Fern

Answer

**Step-by-Step Solution:**

1. **Understanding Gametophytes**: The question asks about the occurrence of leafy gametophytes. Gametophytes are the haploid phase in the life cycle of plants, particularly in bryophytes (mosses, liverworts, and hornworts).

2. **Identifying Bryophyte Groups**: Bryophytes are divided into three main groups: liverworts, mosses, and hornworts. Each group has distinct characteristics in their life cycles.

3. **Characteristics of Liverworts**: In liverworts, the main plant body is the gametophyte, but it does not have a leafy structure. Instead, liverworts typically have a thalloid structure or a flattened body.

4. **Characteristics of Mosses**: In contrast, mosses have a leafy gametophyte. The life cycle of mosses begins with spores that develop into a protonema, which is a filamentous structure. This protonema then develops into the leafy gametophyte.

5. **Examples of Mosses**: Common examples of mosses that exhibit leafy gametophytes include Funeria, Sphagnum, and Polytrichum.

6. **Conclusion**: Since leafy gametophytes are characteristic of mosses and not liverworts or hornworts, the correct answer to the question is "mosses."

**Final Answer**: Leafy gametophyte occurs in mosses.
