Vedclass · Answer

(B) In flowering plants,the zygote is formed by the fusion of a male gamete and an egg cell $(n + n = 2n)$.This diploid zygote undergoes repeated mitotic divisions to develop into an embryo.The primary endosperm cell $(PEC)$,which is triploid $(3n)$ due to the fusion of a male gamete with two polar nuclei,also undergoes repeated mitotic divisions to form the nutritive endosperm tissue.Therefore,both processes involve mitosis.
