What type of cell division ensures that when a cell divides each new cell produced has the same genetic information?
Mitosis.
Cells divide when:
an organism
grows
an organism becomes
damaged
and needs to produce new cells
A growing and dividing cell goes through a series of stages called the
cell cycle.
In mitosis, two cells called
daughter cells
are produced, each identical to the parent cell.

Before a cell can divide it needs to grow and increase the number of sub-cellular structures such as
ribosomes
and
mitochondria.
The DNA replicates to form two copies of each chromosome.
