Vedclass · Answer

(C) The nucellus is a diploid $(2n)$ tissue in the ovule.Given that the number of chromosomes in the nucellus is $2n = 24$,the haploid number $(n)$ is $24 / 2 = 12$.The endosperm in angiosperms is formed by the fusion of one male gamete $(n)$ with two polar nuclei $(n + n)$,resulting in a triploid $(3n)$ structure.Therefore,the number of chromosomes in the endosperm is $3n = 3 	imes 12 = 36$.

If the cells of the nucellus in the angiosperm ovule contain $24$ chromosomes,what will be the number of chromosomes in the endosperm of a self-pollinated flower?
