Topic: NEET PYQ

Answer: B. Full step-by-step solution below.

  1. A16
  2. B24
  3. C32
  4. D8

Correct answer: B

Solution

(b) Synergid cells are haploid (n).
Given synergid chromosome number = 8 (n)
Therefore, sporophytic cells = 2n = 16
Aleurone layer is part of endosperm, which is triploid (3n).
So, chromosomes in aleurone layer = 3 × 8 = 24
