Passive transport The moment of materials through s cell membrane without using energy
diffusion The prosses by witch monocles move from an area of the higher concentration to an area of lower concentration
Osmosis The diffusion of water monocles through a selectively preamble membrane
active transport The movement of materials through a cell membrane using cellular energy
Explain how materials move in and out of cells By diffusion
Know the different types of membrane transport active transport, passive transport and diffusion
Explain the difference between facilitated diffusion and diffusion Diffusion is when small molecules move across the cell membrane and facilitated diffusion is when Adding water filcleited material bring defect in gather cell
