Introduction the movement of water molecules across a semi-permeable membrane is the process of osmosis if there is a solute and a solvent, each containing. Osmosis can be cellular or artificial, so even though we are creating artificial cells in this lab, it is still considered to be osmosis during osmosis, a solvent is trying to get through a selectively permeable membrane to make the concentration of that solvent the same on both sides of the membrane.
