Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The part of the cell cycle that divides the cytoplasm of the cell
A
Synthesis Phase
B
G1 Phase
C
G2 Phase
D
Cytokinesis
Explanation: 

Detailed explanation-1: -Cell division ends as the cytoplasm divides into two by the process of cytokinesis. Except for plants, cytokinesis in eucaryotic cells is mediated by a contractile ring, which is composed of actin and myosin filaments and a variety of other proteins.

Detailed explanation-2: -In plant cells the cytoplasm is divided by the formation of a new cell wall, called the cell plate, between the two daughter cells. Once the daughter cells are separated, cellulose synthesis begins, and the cell plate becomes a primary cell wall.

Detailed explanation-3: -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.
