The cell is 99% water. The surrounding is salty. Where will the water go?

• Into the cell
• Out of the cell
• Equally in & out 

During osmosis

• water moves from high to low concentration
• large or oddly shaped molecules move across a cell membrane
• water moves when energy is used
• proteins are built

Permeable means

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

• in the color
• at the top of cup
