diffusion
Diffusion is a physical process. When it is performed through a selectively permeable membrane, it is called osmosis. Thus osmosis is an appropriate word for movement of water molecules through a selectively permeable membrane and not diffusion.
it is osmosis
Osmosis
Diffusion without a concentration gradient; osmosis with.
Yes, that is very true, especially with osmosis (the passing of water through a selectively permeable membrane).
Osmosis involves the movement of solutes across a selectively permeable membrane by the process of diffusion. In osmosis, water molecules move across the membrane from an area of low solute concentration to an area of high solute concentration in order to equalize the concentration on both sides of the membrane.
Net diffusion of water across a selectively permeable membrane is known as osmosis. In osmosis, water moves from an area of high water concentration to an area of low water concentration in order to equalize the solute concentrations on both sides of the membrane.
The movement of water through a selectively permeable membrane is called diffusion. Water will always diffuse down a concentration gradient, from high solute concentration to low solute concentration.
Osmosis is the diffusion of water molecules through a semi-permeable membrane to equalise osmotic pressure.
semipermeable or selectively permeable.
a dialysis membrane is selectively permeable, it is used in experiments to simulate cellular membranes, and it is permeable to water but not to sucrose.
