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

What is the definition of  Selective Permeability?

• 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 ability of the cell membrane to allow some things to pass through while preventing other things from passing through.
• The movement of molecules from an area of high concentration to a area of low concentration

A person would never have pure water put into their veins in a hospital because their cells would...

• Shrink/Dehydrate

• Expand

• Stay the same

If there is 5 percent water inside a cell and 5 percent water outside a cell

• more water will move inside the cell

• more water will move outside the cell

• There will be no net movement of water, it moves into and out of the cell at the same time.
