Diffusion is high to low it involves no ATP nor does it need protein channels. Osmosis is a type of diffusion, it is the movement of water across a semipermeable membrane. Like diffusion there are no ATP but does need channels. There are a few terms to know when evaluating the levels of the solutes. Isotonic is when the levels are equal compared to the reference. Hypertonic is when the solutes are more than the reference. Hypotonic is less than the solutes from the reference. Another type of movement is facilitated it is when it goes high to low need no ATP and needs channels. Active transport is low to high needs ATP and
