NEET BIOLOGY

Detailed explanation-1: -M phase. During the mitotic (M) phase, the cell divides its copied DNA and cytoplasm to make two new cells. M phase involves two distinct division-related processes: mitosis and cytokinesis.

Detailed explanation-2: -Thus, cytokinesis can be considered to occur in four stages-initiation, contraction, membrane insertion, and completion. The central problem for a cell undergoing cytokinesis is to ensure that it occurs at the right time and in the right place.

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: -This is also often known as cytoplasmic division or cell cleavage. Cytokinesis begins in anaphase in animal cells and prophase in plant cells, and terminates in telophase in both, to form the two daughter cells produced by mitosis.

Detailed explanation-5: -The cytokinesis is of two types, one that occurs in the plant cell is cell plate formation and the other in the animal cell is embryonic cleavage. During the cell division, in plant cells, a new cell wall is formed to separate their daughter cells.
