CELL DIVISION AND CANCEROUS CELLS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
While mitosis splits the contents of the nucleus between the daughter cells, cytokineses
A
uses microfilaments to pinch the cell in two in animals
B
forms a cell plate in plant cells
C
divides the cytoplasm and organelles between the daughter cells.
D
all of these
Explanation: 

Detailed explanation-1: -The cell will continue to grow and many organelles will divide during their phase. Cell growth stops at this stage. Mitosis divides the nucleus into two nuclei, followed by cytokinesis which divides the cytoplasm. Two genetically identical daughter cells result.

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: -When a cell divides during mitosis, some organelles are divided between the two daughter cells. For example, mitochondria are capable of growing and dividing during the interphase, so the daughter cells each have enough mitochondria.

Detailed explanation-4: -Cell division in eukaryotic cells includes mitosis, in which the nucleus divides, and cytokinesis, in which the cytoplasm divides and daughter cells form. Mitosis occurs in four phases, called prophase, metaphase, anaphase, and telophase.

Detailed explanation-5: -A unique feature of the nucleus is that it disassembles and re-forms each time most cells divide. At the beginning of mitosis, the chromosomes condense, the nucleolus disappears, and the nuclear envelope breaks down, resulting in the release of most of the contents of the nucleus into the cytoplasm.
