CELL CLEAVAGE Meaning and
Definition
-
Cell cleavage refers to the process of cell division in which a single cell divides into two or more daughter cells. This essential process plays a fundamental role in both the growth and development of multicellular organisms, as well as in the reproduction of unicellular organisms. Cell cleavage occurs through a series of tightly regulated steps to ensure the accurate distribution of genetic material and cellular components.
During cell cleavage, the parent cell undergoes a series of coordinated changes, including cytoplasmic division and the distribution of organelles. This process is typically initiated by the condensation of the genetic material, followed by the formation of a cleavage furrow or the formation of a cell plate in plant cells. The cleavage furrow gradually deepens and eventually separates the parent cell into two daughter cells. Each daughter cell inherits a complete set of genetic material and a portion of the cytoplasm, organelles, and other cellular components.
Cell cleavage is crucial for various biological processes, including embryonic development, tissue repair, and regeneration. In embryonic development, cell cleavage enables the rapid multiplication of cells, leading to the formation of distinct cell layers and the development of tissues and organs. In tissue repair and regeneration, cell cleavage allows damaged or injured tissues to heal by replacing the damaged cells with new ones.
Overall, cell cleavage is a fundamental process that ensures the growth, development, and maintenance of multicellular organisms, facilitating the formation of tissues and organs, as well as cellular repair and regeneration.
Common Misspellings for CELL CLEAVAGE
Etymology of CELL CLEAVAGE
The etymology of the term "cell cleavage" can be understood by looking at the origin of its individual components.
1. Cell: This word has its roots in the Latin word "cella", which means "small room" or "storeroom". The concept of "cell" was initially used by Robert Hooke in the 17th century when he observed and described the empty chambers he saw in a slice of cork under a microscope. The word "cell" gradually evolved to become a fundamental unit of life, referring to the basic structural and functional unit of all organisms.
2. Cleavage: The term "cleavage" originates from the Old English word "cleofan", which means "to cleave" or "to split". In biology, "cleavage" refers to the process of cell division or the splitting of a cell into two daughter cells.
