NEET Previous Year Question
What would be the number of chromosomes in the cells of the aleurone layer in a plant species with 8 chromosomes in its synergids?
Topic: NEET PYQ
Answer: B. Full step-by-step solution below.
- A16
- B24
- C32
- 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
