Question

Which one of the following pairs of plant structures has haploid number of chromosomes?

• A. Nucellus and antipodal cells
• B. Egg nucleus and secondary nucleus
• C. Megaspore mother cell and antipodal cells
• D. Egg cell and antipodal cells

Answer 1

The correct option is D Egg cell and antipodal cells

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.

So the correct option is D.
