Cytokinesis
The term “cytokinesis” originates from the Greek words “cyto,” referring to hollow or cell, and “kinesis,” signifying movement. Cytokinesis is the final stage of the cell cycle, responsible for the physical division of a parent cell into two daughter cells. This process ensures the equitable distribution of cellular components and organelles, ultimately resulting in the formation of two distinct and genetically identical daughter cells.
In animal cells, cytokinesis involves the formation of a cleavage furrow, where the cell membrane is drawn inward, leading to the separation of the cytoplasm. In plant cells, a cell plate forms, composed of new cell wall materials, dividing the cell into two. Cytokinesis completes the cell cycle and is essential for growth, development, and tissue repair in multicellular organisms.
Mitosis – Overview, Phases, & Significance Class Notes
Cell Cycle M phase, or mitotic phase, is an important stage in the cell cycle responsible for cell division. Mitosis is a process where a single cell divides into two identical daughter cells. The process of mitosis consists of two main steps: karyokinesis, which involves the division of the cell nucleus, and cytokinesis, which is the separation of the cytoplasm and other organelles. The four stages of mitosis are prophase, metaphase, anaphase, and telophase. Cytokinesis completes the cell cycle and is responsible for the physical division of a parent cell into two daughter cells. It helps in the survival and growth of organisms, maintenance of chromosome number, and repair of damaged cells.
