Osmosis Intro Day

What is diffusion?

• When molecules move from a low concentration to a high concentration

• When molecules move from a high concentration to a low concentration.

• When there is no movement of molecules

• When molecules move everywhere regardless of concentration

Osmosis is specifically.....

• diffusion of water molecules through a semi-permeable mebrane from an area of low concentration to an area of high concentration

• the diffusion of particles from an area of high concentration to an area of low concentration

• diffusion of water molecules through a semi-permeable membrane from an area of high concentration to an area of low concentration

• the diffusion of particles from an area of low concentration to an area of high concentration

Equilibrium is when....

• there is a large amount of substance on the inside of the cell and a small amount in the outside solution

• there is a small amount of substance on the inside of the cell and a large amount in the outside solution

• there is an equal amount of substance on either side of the cell membrane

• there are no particles on either side of the the cell membrane

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

Where will the water go?

• Into the cell

• Out of the cell

• Equally in & out - it's isotonic

• There is no water
