Vedclass · Answer

(D) The diploid number $(2n)$ of the plant is $24$.$1$. Pollen grain: These are haploid $(n)$ structures formed after meiosis. Therefore,the number of chromosomes is $24 / 2 = 12$.$2$. Endosperm: In angiosperms,the endosperm is formed by triple fusion,making it triploid $(3n)$. Therefore,the number of chromosomes is $3 	imes 12 = 36$.$3$. Integument: These are part of the ovule and are diploid $(2n)$ in nature. Therefore,the number of chromosomes is $24$.Thus,the correct sequence is $12, 36, 24$.
