Can we say that osmosis is the net movement of water molecules from a region of higher concentration of water to a region of lower concentration of water across a differentially permeable membrane ? Please help to answer . Thanks!

Explanation:

osmosis is the movement of water from higher concentration gradient to lower concentration gradient across a semipermeable membrane. as an example, if a membrane is permeable to a solvent and no to the solute, then the membrane will let the solvent to pass through it thus causing the solution to be more diluted. so yes.. you can say that osmosis is indeed the movement of water from high to low concentration gradient across a 'semipermeable' membrane.

Yes!

Explanation:

Osmosis is basically the net diffusion of solvent molecules down a concentration gradient through a partially permeable membrane, usually through the cell membrane in plants and animals. If we consider the universal solvent, which is water #(H_2O)#, we can also say that osmosis is,

The net movement of water molecules down a concentration gradient through a partially permeable membrane.
