Summary Introduction

Introduction: The movement of materials across the biological membrane may occur either passively or actively. Simple diffusion, osmosis, and facilitated diffusion are the three major types of passive transport. Osmosis is defined as the movement of water or other solvents through a plasma membrane from a region of low concentration of solute to a region of high concentration of solute, tending to equalize the solutes concentration.
