The cell membrane is selectively permeable, which means...

• All materials can enter and leave the cell

• Certain things can enter while others cannot

• The cell manually sorts through all materials

• Only certain cells can interact with the cell.

• simple diffusion

• facilitated diffusion

• active transport

• osmosis
