Detailed explanation-1: -A somatic cell of the pea plant is also diploid in nature. Since the diploid meiocyte has 14 chromosomes, the somatic cell which is also diploid has 14 chromosomes.
Detailed explanation-2: -Mitosis is a type of cell division where the number of chromosomes of the daughter cell will be same as the parent cell. If the parent cell had 14 chromosomes, then the 2 daughter cells will also have 14 chromosomes each.
Detailed explanation-3: -Aleurone layer is the outermost cell layer of the endosperm. The ploidy of the endosperm is triploid. If the root cell which is diploid has 42 chromosomes, so the haploid cell would have 21 chromosomes and triploid would have 3 X 21=63 chromosomes.
Detailed explanation-4: -The number of chromosomes in root cells is 2n while it is n in synergids because it develops by reductional division. Root cells are diploid in nature and thus has 2n = 14. Whereas, synergids are haploid, n = 7. Was this answer helpful?
