Detailed explanation-1: -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-2: -Cytokinesis occurs by a special mechanism in higher-plant cells-in which the cytoplasm is partitioned by the construction of a new cell wall, the cell plate, inside the cell. The position of the cell plate is determined by the position of a preprophase band of microtubules and actin filaments.
Detailed explanation-3: -Cytokinesis is generally defined as the division of the cytoplasm during the M phase of the cell cycle. It is the 2nd step in the M phase. This process also cannot occur without karyokinesis. It is generally the final stage of mitosis, whereby cytoplasm & other cell organelles divide between the two daughter cells.
Detailed explanation-4: -Cytokinesis is the step of the cell cycle in which the cell must faithfully separate the chromosomes and cytoplasm, yielding two daughter cells.
Detailed explanation-5: -cytokinesis, in biology, the process by which one cell physically divides into two cells.
