NEET 2026, Biology Q39: Post-Fertilisation : Structures and Events

NEET2026Biology
Q.

Which one of the following is a triploid cell?

  1. A

    Synergid

  2. B

    Central cell

  3. C

    Zygote

  4. D

    Primary endosperm cell

Solution

Synergids are haploid and the zygote is diploid. The central cell initially has two polar nuclei which fuse before fertilisation to form a diploid secondary nucleus.

The primary endosperm cell (PEC), formed by fusion of the male gamete with the diploid secondary nucleus, is triploid (3n).
