With respect to angiosperms, identify the incorrect pair from the following

Options

A. Antipodals-2n
B. Vegetative cell of male gametophyte-n
C. Primary endosperm nucleus-3n
D. Cells of nucells of ovule-2n.

Answer

To identify the incorrect pair with respect to angiosperms, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understanding the Terms**:
- **Antipodals**: These are cells located at the chalazal end of the embryo sac in angiosperms.
- **Vegetative Cell of Male Gametophyte**: This is part of the pollen grain and is haploid.
- **Primary Endosperm Nucleus**: This is formed after fertilization and is triploid.
- **Cells of Nucellus of Ovule**: These are diploid cells that provide nourishment to the developing embryo.

2. **Evaluating Each Pair**:
- **Antipodals 2N**: This is the first pair to evaluate. Antipodal cells are actually haploid (N), not diploid (2N). Therefore, this pair is incorrect.
- **Vegetative Cell of Male Gametophyte N**: This is a correct pair as the vegetative cell is haploid (N).
- **Primary Endosperm Nucleus 3N**: This is also a correct pair because the primary endosperm nucleus is triploid (3N).
- **Cells of Nucellus of Ovule 2N**: This is a correct pair as the cells of the nucellus are diploid (2N).

3. **Conclusion**:
- The incorrect pair is **Antipodals 2N** because antipodal cells are haploid (N), not diploid (2N).

### Final Answer:
The incorrect pair is **Antipodals 2N**.
