WebNov 3, 2024 · The event of rapid and repeated mitotic division of cells to form numerous nucleated cells is called cleavage. The Planes of Cleavage Cleavage in the egg can occur through different planes. These are described below: Meridional plane WebStep 1: a zygote is the single cell formed when an egg and a sperm cell fuse; the fusion is known as fertilization. Step 2: the first 12-to 24-hours after a zygote is formed are spent in cleavage – very rapid cell division. The zygote’s first priority is dividing to make lots of new cells, so its first few days are spent in rapid mitotic ...
