Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The pinching off of the cell membrane in animal cells to begin the process of cytokinesis?
A
cell wall
B
cell plate
C
cleavage furrow
D
cleavage churro
Explanation: 

Detailed explanation-1: -Cytokinesis is the physical process that finally splits the parent cell into two identical daughter cells. During cytokinesis, the cell membrane pinches in at the cell equator, forming a cleft called the cleavage furrow.

Detailed explanation-2: -Cytokinesis in animal and plant cells. Cytokinesis in an animal cell: an actin ring around the middle of the cell pinches inward, creating an indentation called the cleavage furrow.

Detailed explanation-3: -Cytokinesis is the final act of cell division. In a typical animal mitosis, a cleavage furrow forms at the equatorial cortex after anaphase. This furrow then advances inwards to separate the two daughter cells.

Detailed explanation-4: -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.
