• when molecules move 
• when molecules move from a high concentration to a low.
• no movement 
• molecules move everywhere

Selectively permeable means

• The movement of materials across the cell membrane that requires NO ENERGY from the cell.

• The movement of materials through (or across) the cell membrane

• The movement of molecules from an area of high concentration (where the molecules are more crowded together) to a area of low concentration (where molecules are more spread apart)

• The ability of the cell membrane to allow some things to pass through while preventing other things from passing through.

The diffusion of water through a semi-permeable membrane is called?

• Osmosis
• Cell wall
• Diffusion
• Respiration

What a cell needs to transport particles by active transport?

• Sun
• Wind
• Energy
• Channels
