Diffusion is the process by which molecules or ions spread out from an area of high concentration to an area of low concentration.
Osmosis is the diffusion of water across a partially permeable membrane.
<S>:The rate of diffusion depends on the concentration gradient, with movement occurring from higher to lower concentrations.
Diffusion is the movement of particles from an area of high concentration to low concentration.
non-permeable membranes do not allow any substances to pass through them at all
the movement of molecules from a region of high concentration to a region of low concentration along a concentration gradient
Active Transport is the transport of substances against their concentration gradient using energy (ATP)
Osmosis - The movement of water molecules from a region of high water concentration to a region of low water concentration through Selectively permeable membrane
Constantly moving liquid and gas molecules tend to move from an area of high concentration to an area of lower concentration
Molecules move down a concentrationgradient
Concentration - The greater the concentration gradient the greater the diffusionrate
Temperature - At higher temperatures molecules have more kinetic energy and so move and diffusefaster
Pressure - molecules move quickly from an area of higher to lower pressure
