Lastly, wind plays an important role in pollination in gymnosperms because pollen is blown by the wind to land on the female cones.

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. Q. 41. WebAngiosperms: A group of flowering plants that produce seeds enclosed in an ovary, which matures into a fruit. Gymnosperms and angiosperms have reduced gametophytes that are dependent on the sporophyte, while bryophytes and seedless vascular plants have dominant gametophytes. In gymnosperms and angiosperms, the male gametophyte develops within …
