WebTypes of sexual life cycles. Sexual life cycles involve an alternation between meiosis and fertilization. Meiosis is where a diploid cell gives rise to haploid cells, and fertilization is where two haploid cells (gametes) fuse to form a diploid zygote. What happens between these two events, however, can differ a lot between different organisms ... WebIn all flowering plants, the zygote is formed inside the ovule. In most of the plants, with the formation of zygote, all the parts of the flower except the pistil wither and fall off. In some plants, such as tomato and brinjal, the sepals are persistent and remain attached to the developing fruit.

WebOvulation is the release of eggs from the ovaries.In women, this event occurs when the ovarian follicles rupture and release the secondary oocyte ovarian cells.
