Movement of solvent from lesser to greater solute concentration across a semipermeable membrane.
osmosis
It is also known as bursting of RBC
lysis

hypertonic
What will happen to the cell when placed in a hypotonic solution?
lyze
What type of solution will not damage any cells in the tissue?
isotonic
A cell in a hypertonic solution
loses water
Molecules are transported across a selectively permeable membrane with the aid of carrier molecules
facilitated diffusion
