Vedclass · Answer

(C) The leaf cells are diploid $(2n)$. Given $2n = 24$,therefore the haploid number $(n)$ is $12$.$1$. Synergid cells are haploid $(n)$,so they contain $12$ chromosomes.$2$. Pollen grains are haploid $(n)$,so they contain $12$ chromosomes.$3$. Nucellus cells are diploid $(2n)$,so they contain $24$ chromosomes.$4$. Endosperm in angiosperms is triploid $(3n)$,so it contains $3 	imes 12 = 36$ chromosomes.Thus,the sequence is $12, 12, 24, 36$.
