The cell cycle is important because it allows for ____
A
Reproduction in some organisms
B
Growth and development of organisms
C
Replacement of worn out cells
D
All of thee above
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -Interphase is the most important stage of cell cycle. The cell stays in the interphase for maximum periods. During this phase the cell prepares itself for division. The cell undergoes cell growth and replication during this phase.

Detailed explanation-3: -In order for our bodies to grow and develop, they must produce new cells-and allow for the death of old cells. Cell division is also an essential component of injury repair. If our cells couldn’t divide and create new cells, our bodies could never produce new skin cells to heal road rash, or grow a fingernail back.
