Osmosis
Osmosis Osmosis is defined as the movement of solvent particles (usually water) from a region of high concentration to a region of low concentration through a partially permeable membrane. It is often regarded as a form of diffusion in which only water molecules move. So, water moves from an area where it is in high…
How Osmosis applies to Organisms
How Osmosis applies to Organisms Cell membranes are often compared with a Visking tube as they only allow certain substances to pass through them. This is termed as selective permeability or partially permeable. The body is made up of approximately 70% water. The cytoplasm of cells contains a lot of this water. This means that…
