How will you appreciate cell division that helps in the perpetuation of life? (AS6)

a) Cell division is an important step for the succession of life.


b) According to the improvised Cell Theory- All new cells arise from the pre-existing cells.


c) These new cells arise due to cell division whether it be mitotic or meiotic. The new cells or daughter cells inherit the information and characteristics from their parent cells.


d) Mitotic cell division helps in increasing the number of cells and hence making sure that the population of the species remains stable.


e) Whereas meiotic division helps in keeping the number of chromosomes constant during sexual reproduction, thus maintaining the accuracy of species and enriching them with variations.


f) Hence, we can say that cell division is very useful for the perpetuation of life.
