Definition
  • molecules are attracted to one another
  • molecules constantly move and collide with each other
  • cellular energy forces molecules to collide with eachother
  • cellular energy pumps molecules across the cell membrane
Term

Definition
  •  move across the membrane tot the outside of the cell
  • stop moving across the membrane
  • continue to move across the membrane in both directions
  • move across the membrane to the inside of the cell
Term

Definition
  • osmotic pressure
  • osmosis
  • pinocyosis

  • water to move out of the cell
  • solutes to move into the cell
  • solutes to move out of the the cell
Definition
  • water to move into the cell
  • water to move out of the cell
  • solutes to move into the cell
  • solutes to move out of the the cell
Term
