Cell Biology Basics

Phospholipids bilayer, proteins and cholesterol.

The cell membrane has a fluid semi-permeable barrier against harmful mutations and is used as a getaway for desired materials.

Cytoplasm is a jelly-like substance responsible for supporting the organs and providing nutrients to the cell.
