Does the result of diffusion make the concentration always remain greater inside the membrane?

no it does not make it greater nor fewer inside the cell membrane it's because difussion keeps on going till equilibrium happens. moreover the process difussion allows solutes to be transferred from the more concentration to the less concentration like what happens in glucose between a cell and blood. :)

Which term refers to the diffusion of water throughout a membrane?
Osmosis is the diffusion of water through a membrane (semipermeable) membrane. Water always moves from a high concentration of water to a low concentration of water.
Which term refers to the diffusion of water molecules through a slestively permaeable 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.
When there are different amounts of a substance on either side of the cell membrane what gradient results.?
It is known as a concentration gradient which in diffusion will always flow from areas of high concentration to areas of lower concentrations.
Does diffusion go from high concentration to low concentration?
Yes, they move from high, to low.
What form of passive transport always requires membrane-bound proteins?
Facilitated diffusion

Is Diffusion always from areas of greater to areas of lesser concentration?
During diffusion water moves from a high concentration to a low concentration, when it balances out it tends to stop.

In facilitated diffusion which process does not require energy?
Simple and facilitated diffusion are a part of passive transport. This refers to the movement of molecules, atoms and ions across the cell membrane. In both of these processes, molecules move from areas of high concentration to areas of lower concentration because equilibrium is trying to be maintained in living organisms. Simple diffusion just happens randomly and without any aides. Facilitated diffusion uses proteins in the cell membrane to guide polar molecules and ions in and out of the membrane (always to areas of lower concentration) and DOES NOT require ENERGY.Only active diffusion requires energy.

What conditions are necessary for diffusion to take place?
The conditions necessary for diffusion is firstly a semi permeable membrane, and a concentration gradient for the movement of molecules from higher concentration to lower concentration. The size of the molecules should be small enough to pass easily through the membrane.
Does diffusion always have to be though a membrane?
yes
Is it from high concentration to low that particles move across a membrane move?
Yes. It is called Osmosis. Particles move across the membrane in order to balance the concentration of particles on both sides of the membrane. Since the membrane tends to block the larger particles, its the smaller molecules that move, so what happens across membranes is that the motion (of say water) is from low concentration toward higher - but the result is to even the concentration on both sides of the membrane, Pure diffusion is always from higher concentration to lower.
What is faciillitated diffusion?
Facilitated diffusion is diffusion that occurs not through the cell membrane directly but through protein channels within the cell membrane. They are often, although not always, substrate specific.
