Cell division is significant in the following ways
i. Cell multiplication: Cell division is a means of cell multiplication or the formation of new cells from pre-existing cells.
ii. Continuity: It maintains continuity of living matter generation after generation.
iii. Multicellular organisms: The body of a multicellular organism is formed of innumerable cells. They are formed by repeated divisions of a single cell or zygote. As the number of cells increases, many of them begin to differentiate, form tissues and organisms.
iv. Cell size: Cell division helps in the maintenance of a particular cell size which is essential for efficiency and control of cell activities.
v. Genetic similarity: The common type of cell division or mitosis maintains the genetic similarity of all the cells in an individual despite being different, i.e., structurally and functionally.
