1 Selectively permeable membranes
The s s molecules are too large to pass through the s p membrane 2) A c gradient exists between the outside of the cell and the inside 3) There is a h concentration of water molecules on the outside of the cell than on the inside 4) Water molecules diffuse from an area of h concentration to an area of l concentration 5) This movement of water, in response to a concentration gradient, through a selectively permeable membrane is called O Selectively permeable membranes Sucrose sugar higher low osmosis Selectively permeable high Concentration The s s molecules are too large to pass through the s p membrane 2) A c gradient exists between the outside of the cell and the inside 3) There is a h concentration of water molecules on the outside of the cell than on the inside 4) Water molecules diffuse from an area of h concentration to an area of l concentration 5) This movement of water, in response to a concentration gradient, through a selectively permeable membrane is called O Selectively permeable membranes Sucrose sugar higher low osmosis Selectively permeable high Concentration The s s molecules are too large to pass through the s p membrane 2) A c gradient exists between the outside of the cell and the inside 3) There is a h concentration of water molecules on the outside of the cell than on the inside 4) Water molecules diffuse from an area of h concentration to an area of l concentration 5) This movement of water, in response to a concentration gradient, through a selectively permeable membrane is called O Sucrose sugar higher low osmosis Selectively permeable high Concentration
