The zygote develops into a sporophyte, producing stems and roots. The stems produce leaves which shade the gametophyte and it soon dies (Fig. 9) WebThe generative cell travels through the tube to the egg and divides mitotically to form two sperm cells. One sperm fertilizes the egg cell, forming a diploid zygote; the other sperm fuses with the two polar nuclei, forming a triploid cell that develops into the endosperm, which serves as a source of nutrition for the developing embryo.
