NEET Botany Question (2026) — Solution

Question

Which one of the following is a triploid cell ?

Options

  1. A. Synergid
  2. B. Central cell
  3. C. Zygote
  4. D. Primary endosperm cell

Answer

D. Primary endosperm cell

Step-by-step solution

Synergids are haploid (n) cells present in the embryo sac. The central cell contains two polar nuclei (n + n) which fuse to form a diploid secondary nucleus (2n). The zygote is a diploid (2n) cell formed by the fusion of a male gamete (n) with the egg cell (n). The primary endosperm cell is formed by the fusion of a male gamete (n) with the two polar nuclei or secondary nucleus (2n) of the central cell. This process is called triple fusion, resulting in a triploid (3n) primary endosperm cell. Answer: Primary endosperm cell
