When cells are damaged, cell division helps clear out the damaged cells

|
|
If a cell is damaged, cell division creates new organelles inside it

|
|
If a cell is broken, it can be “put back together”

|
If a cell is damaged, cell division can make a new cell to replace it

Detailed explanation-1: -Cells also divide in order to replace damaged or worn-out cells. Most cell division produces genetically identical cells, meaning they have the same DNA. The process of mitosis, which ensures that each nucleus in each resulting cell after cell division is genetically identical, is essential to this process.
Detailed explanation-2: -Significance of Cell Division Renewing of damaged cells. Production of new cells from older ones. Maintains the total number of chromosomes. Provides more cells for growth and development.
Detailed explanation-3: -When cells become damaged or die the body makes new cells to replace them. This process is called cell division. One cell doubles by dividing into two. Two cells become four and so on.
Detailed explanation-4: -Mitosis is the process where two identical daughter cells are formed from a single cell by the division of cells. The major purpose for cell division in mitosis is for the growth and for replacing the worn-out cells.
Detailed explanation-5: -For example plants, animals depend on cell division for their growth by addition of new cells. It is also used for repairing the injured tissues or replacing the worn-out tissue by regenerating new cells. Mitosis refers to the splitting of chromosomes in the eukaryotic cells during the cell division process.
