Q. What would be the number of chromosomes of the aleurone cells of a plant with 42 chromosomes in its root tip cells?
A) 21
B) 42
C) 63
D) 84
Explanation
[Solution from source] Root tip cells are diploid, so 2n = 42 and n = 21. The aleurone layer is the outer layer of the endosperm, which is triploid: 3n = 3 × 21 = 63. 42 is the diploid count and would be the trap. Answer (3).
