Select incorrect statement for diplontic life cycle
1 Diploid sporophyte is the photosynthetic and dependent phase of the plant
2 The gametophytic phase is represented by the single to a few-celled haploid gametophyte
3 Diploid sporophyte is the dominant, photosynthetic and independent phase of the plant
4 All spermatophytes follow this pattern

Options

A. Diploid sporophyte is the photosynthetic and dependent phase of the plant
B. The gametophytic phase is represented by the single to a few-celled haploid gametophyte
C. Diploid sporophyte is the dominant, photosynthetic and independent phase of the plant
D. All spermatophytes follow this pattern

Answer

To solve the question regarding the incorrect statement for the diplontic life cycle, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding Diplontic Life Cycle**:
- In the diplontic life cycle, the dominant phase is the diploid sporophyte. This phase is characterized by having two sets of chromosomes (2n).

2. **Analyzing Option 1**:
- **Statement**: "Diploid sporophyte is the photosynthetic and dependent phase of the plant."
- **Evaluation**: This statement is incorrect because the diploid sporophyte is actually the dominant, independent, and photosynthetic phase of the plant, not dependent.

3. **Analyzing Option 2**:
- **Statement**: "The gametophytic phase is represented by the single to few-celled haploid gametophyte."
- **Evaluation**: This statement is correct. In the diplontic life cycle, the gametophyte is indeed reduced and typically consists of a few cells.

4. **Analyzing Option 3**:
- **Statement**: "Diploid sporophyte is the dominant, photosynthetic and independent phase of the plant."
- **Evaluation**: This statement is correct. The diploid sporophyte is the main phase of the plant that is photosynthetic and independent.

5. **Analyzing Option 4**:
- **Statement**: "All spermatophytes follow this pattern."
- **Evaluation**: This statement is also correct. Spermatophytes (seed plants) like gymnosperms and angiosperms exhibit the diplontic life cycle.

6. **Conclusion**:
- The only incorrect statement among the options is **Option 1**: "Diploid sporophyte is the photosynthetic and dependent phase of the plant."

### Final Answer:
The incorrect statement for the diplontic life cycle is **Option 1**.
