Here's a breakdown of cytokinesis:

* What happens: Cytokinesis is the physical process where the cytoplasm of a single eukaryotic cell divides into two daughter cells. This happens after mitosis (nuclear division) or meiosis (reduction division) has occurred.

* Importance: It ensures that each daughter cell receives a complete set of organelles and cytoplasm, enabling them to function independently.

* Process: The process of cytokinesis varies slightly in animal and plant cells:

* Animal Cells: A cleavage furrow forms at the cell's equator. This furrow, made of microfilaments (mainly actin), pinches inward, gradually dividing the cytoplasm.

* Plant Cells: Plant cells have rigid cell walls, so a cell plate forms between the two daughter nuclei. The cell plate, made of vesicles containing cell wall material, expands until it fuses with the existing cell wall, separating the two daughter cells.
