While molecules in diffusion move down a concentration gradient, molecules during osmosis both move down a concentration gradient as well as across it. Both diffusion, and osmosis are types of passive transport, which do not require help.

In hypotonic solutions, when water moves into the cell they burst, which is known as lists. A hypersonic solution…...
