Q. What would be the number of chromosomes in the cells of the aleurone layer in a plant species with 8 chromosomes in its synergids ?
A) 16
B) 24
C) 32
D) 8
Explanation
[Solution from source] Synergids are cells of the embryo sac and are haploid, so n = 8 here. The aleurone layer is the outermost layer of the endosperm, which is triploid (3n), giving 24 chromosomes. 16 would be the diploid (2n) count of somatic cells, not endosperm. Answer (2).
