Summary Introduction
Introduction:
Every living organism is made up of a cell. The cell is the basic “fundamental unit” of life. The cell comprises three major regions. These major regions are “plasma membrane, cytoplasm, and nucleus.” The nucleus contains chromosomes that are thread like extensions.
