During development, the process of cellular division without the addition of cytoplasm or any increase in size is known as cytokinesis.
Cytokinesis is the final stage of the cell cycle, following mitosis or meiosis, in which the cytoplasm divides, resulting in two daughter cells. This process ensures that each daughter cell receives a complete set of genetic material. Cytokinesis differs depending on the type of cell being divided.
In animal cells, cytokinesis typically involves the formation of a contractile ring, made up of actin and myosin proteins, near the equator of the cell. This contractile ring contracts, like a drawstring, eventually pinching the cell in two and forming a cleavage furrow.
In plant cells, the presence of a rigid cell wall makes cytokinesis more complex. Instead of a contractile ring, a cell plate forms in the middle of the cell. The cell plate consists of vesicles containing cell wall materials, such as cellulose, which are brought by the Golgi apparatus. These vesicles fuse together and gradually elongate to form a new cell wall, dividing the cytoplasm into two daughter cells.
In both animal and plant cells, cytokinesis ensures the proper distribution of cellular contents and organelles between the daughter cells, allowing for the continued growth, repair, and reproduction of organisms.
