During diffusion

• substances (things) moves from high to low concentration
• water moves when energy is used
• large or oddly shaped molecules move across a cell membrane
• water moves from high to low concentration

When both inside and outside of a cell have the same amount of water it is said that the cell has reached a state of ___________.

• osmosis
• equilibrium
• diffusion
• hypertonic

Permeable means

• things can pass through
• the concentration levels are different
• it is permanent
• things are stuck

Where will the water go?

• Into the cell

• Out of the cell

• Equally in & out - it's isotonic

• There is no water
