WebThe embryonic plant is diploid and it develops from a zygote formed by the union of egg and sperm. The seed coat is also diploid and it also is derived from a sporophyte plant, but it is an earlier sporophyte generation than the embryo. WebIn angiosperms, zygote is diploid while primary endosperm cell is triploid. Explain. Ans. A zygote is formed by the fusion of haploid male gamete with the haploid egg to form a diploid cell; whereas, primary endosperm nucleus (PEN) is formed by the fusion of haploid male gamete with two haploid polar nuclei, forming a triploid nucleus.

WebThe male and female gametophyte structures are present on separate male and female cones in gymnosperms, whereas in angiosperms, they are a part of the flower. Lastly, wind plays an important role in pollination in gymnosperms because pollen is blown by the wind to land on the female cones.
