Question

Which of the following pair of cells are haploid?

• A. Nucleus and antipodals.
• B. Polar nuclei and Nucleus.
• C. Egg cell and antipodals.
• D. Etc.

Hint:

In plants, the egg cell and antipodal cells are haploid, while the central cell and polar nuclei are typically diploid.

Answer 1

The Correct Option is C

In this question, we are asked to identify which pair of cells are haploid. Haploid cells contain a single set of chromosomes. - The egg cell is a haploid cell, as it contains half the number of chromosomes required for fertilization. - Antipodal cells, which are formed in the female gametophyte, are also haploid. On the other hand: - The nucleus and polar nuclei are diploid (contain two sets of chromosomes). - The nucleus of the ovule is also diploid. Therefore, the correct answer is option (C), where both the egg cell and antipodal cells are haploid.
