Semi permeable membrane means a very thin layer of material which allows some molecule to pass through them and prevent some molecule to pass through them.
Osmosis is the passage of water from a dilute solution via a membrane which is semi permeable to a more concentrate solution.
So the membrane should be semi-permeable so as to only allow the movement of H2O molecules and not the other molecules of the mixture.

What is the need for a semi permeable membrane?
we need a semipermeable membrane for a process called osmosis...
The diffusion of water across a semipermeable membrane is called?
When water diffuses through a semipermeable membrane, such as a cell, it is called osmosis. In osmosis the concentration of water will differ on one side of the membrane from that of the other side. Water molecules will tend to diffuse from the high concentration side to the lower.
What is the movement of water across a semipermeable membrane from an area of high water concentration to an area of low concentration called?
Osmosis
What is the definition for osmosis?
# a physical chemistry,cell biology. ------------------------------ Movement of solvent through a semipermeable membrane so as to equalize the concentration of solute across the membrane.
Water molecules spreading through a membrane with a change in cell size is an example of what?
Water molecules spreading through a membrane with a change in cell size is an example of osmosis. In osmosis fluid passes both in and out of the semipermeable membrane in osmosis, but usually there's a net flow in one direction.
Why does osmosis require a semipermeable membrane while diffusion does not?
yes
The diffusion of water through a semipermeable membrane is?
Osmosis...
Is osmosis a process of cellular respiration?
No, osmosis happens anywhere there is a semipermeable membrane.
What is the name for the diffusion water across a semipermeable membrane?
osmosis
What is the name for the diffusion of water across semipermeable membrane?
osmosis
Does osmosis require a carrier?
NO. Osmosis( by definition) is the DIFFUSION of water from a high concentration gradient to a low concentration gradient across a semipermeable membrane. As diffusion is a form of passive transport, it doesnt require a carrier
What is the need for a semi permeable membrane?

Diffusion of solvent particles across a semipermeable membrane?
Osmosis is the diffusion of water through a semi-permeable membrane, such as that surrounding a cell. Semipermeable indicates that the membrane will allow certain thing to pass through it while preventing others.
What is the diffusion of water across a semipermeable memberane?
Diffusion of water across a semipermeable membrane is a type of simple diffusion given the special name of osmosis.
What moves through a semipermeable membrane into an area of what concentration?
Water moves through a semipermeable membrane from an area of high to low concentration. This is called osmosis.
Examples of osmosis?
Osmisis is the movement or diffusion of water across a semipermeable membrane
What is the easiest way to define osmosis?
The movement of water across a semipermeable membrane.
