Question

Which of the following pair has haploid structures?

• A. Nucellus and antipodal cells
• B. Antipodal cells and egg cell
• C. Antipodal cells and megaspore mother cell
• D. Nucellus and primary endosperm nucleus

Answer 1

The correct option is B Antipodal cells and egg cell

Nucellus has 2n structure antipodal has n

antipodal cells-n, egg cell-n

Antipodal cells-n, Megaspore mother cell-2n

Nucellus-2n, Primary endosperm nucleus-3n

In egg cell and antipodal cells have haploid number of chromosomes. In angiosphere single diploid megaspore mother cell matures in an ovule. By meiosis it forms 4 megaspores this is also called haploid.
