Select the incorrect statement from the following.

Options

A. The dominant phase in the life cycle of pteridophytes is sporophyte
B. The dominant phase in the life cycle of pteridophytes is gametophyte.
C. The dominant phase in the life cycle of gymnosperms is gametophyte.
D. The dominant phase in the life cycle of angiosperms is sporophyte

Answer

To solve the question of selecting the incorrect statement from the provided options regarding the life cycles of Pteridophyta, Gymnosperms, and Angiosperms, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Pteridophyta**:
- Pteridophyta, which includes ferns, has a life cycle that is haplodiplontic, meaning it has both a sporophyte (diploid) and a gametophyte (haploid) stage.
- In Pteridophyta, the sporophyte is the dominant phase, but both phases are present.

2. **Analyzing Gymnosperms**:
- Gymnosperms also have a haplodiplontic life cycle, but in these plants, the sporophyte is the dominant phase.
- The gametophyte is reduced and dependent on the sporophyte for nutrition.

3. **Examining Angiosperms**:
- Angiosperms, like Gymnosperms, have a dominant sporophyte phase.
- The sporophyte is the main plant body, and the gametophyte is highly reduced and found within flowers.

4. **Identifying the Incorrect Statement**:
- The statement that claims "the dominant phase in the life cycle of Gymnosperm is gametophyte" is incorrect.
- In reality, the dominant phase in Gymnosperms is the sporophyte.

5. **Conclusion**:
- Therefore, the incorrect statement among the options is the one that states the dominant phase in Gymnosperms is the gametophyte.

### Final Answer:
The incorrect statement is: "The dominant phase in the life cycle of Gymnosperm is gametophyte."
