its not diffusion at all, but i think you mean osmosis. it has nothing to do with water concentration so it is a completely distinct mechanism.
osmosis works as the amount of free water decreases as the amount of solute increase. we refer to the proportion of water in this free state as Ψ (psi). solutions with a lower Ψ have more solutes in them and therefore water will travel across a partially permiable membrane down the Ψ gradent, until the amount of free water is the same. the maximum Ψ possible (for comletely pur water) is 0.

What is cell osmosis?
Movement of water molecules.
Why does a cell stay the same size in an isotonic solution?
There is no net movement of water molecules in and out of the cell.
Is defusion water going through the cell?
Diffusion is a physical process that involves the spontaneous movement of molecules from where they are plentiful to where they are scarce. This process could occur in either directions and is dependent on the direction of the concentration gradient. If for example, there are more water molecules outside the cell, then the water molecules would diffuse into the cell and if there are more water molecules inside the cell, they would diffuse out of the cell. I both cases, the water molecules have to travel through the cell membrane, which brings us to the next concept: Osmosis - which is the diffusion of molecules along a concentration gradient through a semi-permeable membrane (the cell membrane)
Diffusion is defined as a movement of molecules?
Is Diffusion the movement of molecules from a greater to a lesser concentration.
Water molecules will no longer pass through the semipermeable membrane once equilibrium is reached true or false?
False. There will still be movement of water molecules across the membrane, but there will be no net movement. This means that the number of molecules coming into the cell will equal that going out, and equilibrium will therefore be maintained.
What describes the movement of water molecules in and out of a cell?
osmosis
Which term describes the movement of water molecules into and out of the cell?
Osmosis is the movement of water particles from an area of high concentration to an area of low concentration, across a semi-permeable membrane.
What is cell osmosis?
Movement of water molecules.
What property describes the plasma membrane's ability to regulate movement of molecules into and out of the cell?
permeability
Which term describe the movement of water molecules in and out of a cell?
its not homeostasis
Which term describes the movement of water molecule in and out of the cell?
The movement of water through a semipermeable membrane is called osmosis.
What terms describes the movement of water molecule in and out of cell?
The movement of water through a semipermeable membrane is called osmosis.
Why does a cell stay the same size in an isotonic solution?
There is no net movement of water molecules in and out of the cell.
What is the movement of water molecules through a sectively-permeable cell membrane?
osmosis
Is this correct no energy is required for the movement of water molecules across the cell membrane?
No
What might happen if a disease caused a plasma membrane to thicken?
decreased movement of molecules entering the cells decreased movement of molecules entering the cells
Under what conditions would the net movement of water be into the cell?
If there was less H20 molecules in the cell than outside
