hypertonic; hypotonic

permeable membrane

allows things to pass through it

Osmosis occurs usually with water being the _____ in the solution in the context of a _____ membrane.

solvent; semi permeable

In osmosis, water will travel to the solution with the _____ concentration of solute in order to try and make the two solutions reach ______.

higher; equilibrium

In osmosis through a semi permeable membrane, try to think of water as the solute because, in terms of the actual solute, it is traveling from the _____ solution to the ______ solution.
