Leafy gametophytes occur in

Options

A. Pteridophytes
B. Gymnosperms
C. Bryophytes
D. Angiosperms.

Answer

To solve the question "Leafy gametophytes occur in," we need to analyze the options provided: pteridophytes, gymnosperms, bryophytes, and angiosperms. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand the Life Cycle of Plants
- Plants have two main stages in their life cycle: the sporophytic stage and the gametophytic stage.
- The sporophytic stage is diploid (2N), while the gametophytic stage is haploid (N).

**Hint:** Remember that the gametophytic stage is where gametes are formed.

### Step 2: Identify the Dominance of Stages in Different Plant Groups
- In some plants, the sporophytic stage is dominant, while in others, the gametophytic stage is more prominent.
- For example, in bryophytes, the gametophyte is the dominant stage, while in pteridophytes, gymnosperms, and angiosperms, the sporophyte is dominant.

**Hint:** Focus on which plant group has a prominent gametophytic stage.

### Step 3: Analyze Each Option
- **Pteridophytes:** These plants have a dominant sporophytic stage and do not exhibit leafy gametophytes.
- **Gymnosperms:** These also have a dominant sporophytic stage and do not have leafy gametophytes.
- **Angiosperms:** Similar to gymnosperms, they have a dominant sporophytic stage and lack leafy gametophytes.
- **Bryophytes:** This group is characterized by a prominent leafy gametophyte stage, which is the main form of the plant.

**Hint:** Look for the group that is known for having a leafy structure in its gametophyte.

### Step 4: Conclusion
- Based on the analysis, the correct answer is **bryophytes**, as they are the only group that has a prominent leafy gametophyte stage.

**Final Answer:** Leafy gametophytes occur in **bryophytes**.
