Meiosis and unequal cytoplasmic division
Web1 mrt. 2024 · Cytokinesis is the process whereby the cytoplasm of a parent cell is divided between two daughter cells produced either via mitosis or meiosis. This is also often known as cytoplasmic division or cell cleavage. Cytokinesis begins in anaphase in animal cells and prophase in plant cells, and terminates in telophase in both, to form the two ... Web2 feb. 2024 · Meiosis Stages Diagram. Meiosis involves two successive stages or phases of cell division, meiosis I and meiosis II. Each stage includes a period of nuclear division or karyokinesis and a cytoplasmic division or cytokinesis. Although not a part of meiosis, the cells before entering meiosis I undergo a compulsory growth period called interphase.

Web20 sep. 2024 · Cytokinesis is the physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells. It occurs concurrently with two types of nuclear division called mitosis and meiosis, which occur in animal cells. Which is the last part of cell division?
