Vedclass · Answer

(B) The nucellar cells are diploid $(2n)$. Given $2n = 24$,the haploid number $(n)$ is $12$.$1$. Pollen grains are haploid $(n)$,so they contain $12$ chromosomes.$2$. The endosperm in angiosperms is formed by triple fusion and is triploid $(3n)$. Thus,$3 	imes 12 = 36$ chromosomes.$3$. The embryo is formed by the fusion of a male gamete and an egg cell,making it diploid $(2n)$. Thus,$2 	imes 12 = 24$ chromosomes.Therefore,the sequence is $12, 36, 24$.

If the number of chromosomes in the nucellar cells of an angiosperm is $24$,what will be the number of chromosomes in the pollen grain,endosperm,and embryo,respectively?
