What is the term for the movement of water across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration?

Diffusion Laminar flow There is no term. Osmosis

Osmosis takes place when water moves from a region of higher water potential to a region of lower water potential through a semi-permeable membrane, which allows water to pass through but not ions in solution.

Bonus: Can you list out some differences between diffusion and osmosis?

Osmosis - movement of water to even out concentration gradient

Diffusion - movement of solute to create a homogenous solution

Osmosis occurs only in selectively permeable membrane. Whereas diffusion doesn't require that.

Correct. Can you tell more?

@Nihar Mahajan – Yeah. Osmosis requires a water medium, but diffusion doesn't require any specific medium.

@Nihar Mahajan – We were taught about all this last year. . .
