low concentration
Osmosis is not a molecule. It is the flow of water through cell membranes from areas of high concentration to areas of low concentration.
Diffusion is the movement of molecules from a high concentration to a low concentration without using ATP (energy). A related term: Osmosis is the movement of water molecules from a high concentration to a low concentration without using ATP (energy). In contrast, active transport is the movement of molecules from a low concentration to a high concentration but DOES use ATP (energy).
An area of higher concentration to an area of lower concentration.
Passive transport moves molecules from a high to low concentration gradient.
Osmosis
Diffusion is the movement of molecules from an area of high concentration to an area of low concentration.
Movement of molecules 4m higher to lower concentration is called osmosis
Diffusion.
Diffusion.
When molecules of water move from high to low concentration, it is referred to as OSMOSIS.When solute molecules move from high to low concentration, it is referred to as DIFFUSION.
high concentration to low concentration
