In an angiosperm male plant is diploid

WebThe pollen grains carry the male gametes of the plant. The small haploid (1 n) cells are encased in a protective coat that prevents desiccation (drying out) and mechanical damage. Pollen can travel far from the sporophyte that bore it, spreading the plant’s genes and avoiding competition with other plants.

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. WebMay 4, 2024 · Both the micropyle and megasporangium are diploid tissue of the sporophyte and are connected to the ovary wall by a region of tissue called the funiculus.
