Membrane Transport

Membrane Transport

​Why is it important to understand membrane transport?

The purpose of cell transport is to move molecules into or out of the cell.
Cell transport occurs across the cell membrane, which is a thin barrier that separates the cell from its environment.
Cell transport is important because it allows cells to bring in oxygen and nutrients and release waste.

Types of Solutions

​Exchange between cells is based on the concentration gradient between cells.
