ANATOMY

Detailed explanation-1: -During cytokinesis, the cytoplasm splits in two and the cell divides. The process is different in plant and animal cells, as you can see in Figure 7.3. 8. In animal cells, the plasma membrane of the parent cell pinches inward along the cell’s equator until two daughter cells form.

Detailed explanation-2: -In animal cells, the area of the cell membrane that pinches inward to separate the dividing cell into two cells is called the cleavage furrow.

Detailed explanation-3: -In animals, cell division occurs when a band of cytoskeletal fibers called the contractile ring contracts inward and pinches the cell in two, a process called contractile cytokinesis.

Detailed explanation-4: -Cytokinesis is the process following the division of the nucleus, the cytoplasm and plasma membrane are divided, resulting in two cells, each with its own nucleus and cytoplasm surrounded by a plasma membrane. It occurs in both plant cells and animal cells.

Detailed explanation-5: -At the cytokinesis furrow, it is the actin-myosin contractile ring that drives the cleavage process, during which cell membrane and wall grow inward, which eventually pinches the mother cell in two.
