Plasma Membrane Transport

Which type of transport moves molecules from an area of HIGH concentration to an area of LOW concentration?

• Active

• Passive

The cell membrane forms a boundary between the inside and the outside of the cell. It's job is to

• give the cell structure and support

• maintain homeostasis

• allow all things to enter the cell

• not allow anything to enter the cell
