CELL DIVISION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The division of the nucleus is ____ and the division of the cell membrane/cytoplasm is ____
A
mitosis and meiosis
B
mitosis and cytokinesis
C
cytokinesis and mitosis
D
meiosis and mitosis
Explanation: 

Detailed explanation-1: -Mitosis is nuclear division during which duplicated chromosomes are segregated and distributed into daughter nuclei. Usually the cell will divide after mitosis in a process called cytokinesis in which the cytoplasm is divided and two daughter cells are formed.

Detailed explanation-2: -Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. During cell division, mitosis refers specifically to the separation of the duplicated genetic material carried in the nucleus.

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.

Detailed explanation-4: -Mitotic cell division is only complete after the cell completely divides into two cells. After mitosis is complete, the cell with two nuclei undergoes cytokinesis to divide the cytoplasm, thereby completing mitotic cell division.

Detailed explanation-5: -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.
