COMMON STRUCTURE OF A CELL
Common parts of a typical cell
1. Cell membrane/plasma membrane/plasmalemma
● For support and protection, the outermost covering of animal cell, semi-
permeable, thin, and flexible
● It is composed of protein and phospholipids
● Functions
o Maintains the shape of the cell
o Contains the cell contents
o Prevents the contents of one cell from mixing with those of other cells
o Controls the entrance and exit of materials in the cell
