What is osmosis
Osmosis is the diffusion of water molecules from a region of high water concentration to region of low water concentration through a selectively permeable membrane
What’s does sucrose mean
Low water
What’s happens to cell in low water
Shrink
What is diffusion
Diffusion is the movement of molecules down a concentration gradient from a region of high concentration to a region low concentration until the concentration becomes equal
