Cell Transport Flashcards
(6 cards)
Selectively Permeable
this means that the cell membrane will let some things in and out, but not others
Passive Transport
when items move across the cell membrane WITHOUT the cell using energy
Diffusion
when particles move from an area of high concentration to low concentration
Equilibrium
when there is an equal number of particles on both sides of the membrane
Osmosis
diffusion of water molecules into or out of a cell
Facilitated Diffusion
when a protein in the membrane is needed to move a particle into or out of the cell from high to low concentration
