Detailed explanation-1: -Significance of Cell Division Production of new cells from older ones. Maintains the total number of chromosomes. Provides more cells for growth and development. Repairs and controls the damage caused to the cells.
Detailed explanation-2: -Cells must replicate their DNA before they can divide. This ensures that each daughter cell gets a copy of the genome, and therefore, successful inheritance of genetic traits. DNA replication is an essential process and the basic mechanism is conserved in all organisms.
Detailed explanation-3: -The most basic function of the cell cycle is to duplicate accurately the vast amount of DNA in the chromosomes and then segregate the copies precisely into two genetically identical daughter cells. These processes define the two major phases of the cell cycle.
Detailed explanation-4: -Stem cells provide a pool of dividing cells that the body uses to restock damaged or old cells. Stem cells are a kind of ‘starter cell’. They have the potential to develop into different cell types in the body.
