Vedclass · Answer

(B) Integuments are part of the sporophyte and are diploid $(2n)$. Given that the chromosome number in integuments is $10$,we have $2n = 10$,which implies $n = 5$.Synergids are haploid $(n)$ cells found in the embryo sac,so their chromosome number is $5$.The definitive nucleus (secondary nucleus) is formed by the fusion of two polar nuclei,making it diploid $(2n)$. Therefore,its chromosome number is $10$.Antipodal cells are haploid $(n)$ cells found in the embryo sac,so their chromosome number is $5$.Thus,the chromosome numbers for synergids,definitive nucleus,and antipodal cells are $5, 10, 5$ respectively.
