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

There are three antipodal cells which are haploid. The antipodal cells are located at the opposite end to the micropyle in the embryo sac.

The other opposite end of the embryo sac is the egg cell which has two synergid cells flanking. The egg cells are also haploid.
Hence, both egg cells and antipodal cells have haploid number of chromosomes.

Nucellus-2n, antipodal cells-n,
Antipodal cells-n, egg cell-n,
Antipodal cells-n, megaspore mother cell-2n,
Nucellus-2n, primary endosperm nucleus-3n

Antipodal and egg cell are the product of meiotic division and rest are not.

So the correct option is B.
