Which best describes the difference between osmosis and diffusion? Osmosis is the movement of particles from a high to a low particle concentration, while diffusion is the movement of water from a high to a low water concentration. Diffusion is the movement of particles from a high to low particle concentration, while osmosis is the movement of water from a high to a low water concentration. Diffusion is the movement of particles from a low to a high particle concentration, while osmosis is the movement of water from a low to a high water concentration. Osmosis is the movement of particles from a low to a high particle concentration, while diffusion is the movement of water from a low to a high water concentration.

## Step 1<br />The problem is asking us to identify the correct description of the difference between osmosis and diffusion. <br /><br />## Step 2<br />Osmosis is a specific type of diffusion that involves the movement of water molecules across a semi-permeable membrane. This movement is from an area of lower solute concentration to an area of higher solute concentration. <br /><br />## Step 3<br />Diffusion, on the other hand, is a general process where particles move from an area of higher concentration to an area of lower concentration. This process does not require a semi-permeable membrane and can occur in gases, liquids, or solids.<br /><br />## Step 4<br />By comparing the definitions of osmosis and diffusion, we can see that option B correctly describes the difference between the two processes.
