CELLULAR DIVISIONS Meaning and
Definition
-
Cellular divisions refer to the processes by which cells undergo division, resulting in the formation of new cells. These divisions play a crucial role in the growth, development, and maintenance of all living organisms.
The most common type of cellular division is called mitosis, which occurs in somatic cells, responsible for the growth and repair of body tissues. Mitosis involves a series of complex steps, including the replication and distribution of DNA, followed by the separation of the replicated chromosomes into two daughter cells with identical genetic material. This ensures that each new cell receives the complete set of genetic information necessary for proper functioning.
Another form of cellular division is meiosis, which occurs in specialized cells, such as germ cells, that give rise to eggs and sperm. Meiosis is a two-step process involving two rounds of division, resulting in the production of four non-identical daughter cells with half the number of chromosomes as the parent cell. This enables the creation of genetic diversity, as these cells are involved in sexual reproduction.
Cellular divisions are tightly controlled by a complex network of proteins and regulatory mechanisms to ensure proper cell growth, differentiation, and proliferation. Disruptions or errors in cellular divisions can lead to various disorders, including cancer, developmental abnormalities, and genetic diseases.
In summary, cellular divisions are the fundamental processes through which cells divide, ensuring proper growth, maintenance, and reproduction in living organisms.

Etymology of CELLULAR DIVISIONS
The word "cellular" originates from the Latin word "cellula", meaning "small room" or "small chamber". It was first used in the context of biological cells by Robert Hooke, who observed small compartments resembling the rooms of a monastery in a slice of cork under a microscope in 1665. These compartments were named cells because they reminded Hooke of the monks' living quarters.
The term "division" in this context comes from the Latin word "divisio", meaning "partition" or "division". It refers to the process of splitting or dividing larger cells into smaller daughter cells during cell replication or reproduction.
Therefore, the etymology of "cellular divisions" stems from "cellula" and "divisio", combining to describe the process in which cells split into smaller units.
