Cell theory is that part of biology which describes the principles and characteristics on which cells survive. Cell, being the most basic and fundamental unit of life it is of extreme importance in the world of biology. It is the smallest unit of life that can live and replicate independently.

They all contain their own genetic information and share a common ancestor.
