Final answer:
Osmosis is the term used to describe the movement of water through a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration.
Step-by-step explanation:
The term used to describe the movement of fluid through a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration is osmosis.
Osmosis is a special case of diffusion that is specific to water, which moves from an area where it is more concentrated to one where it is less concentrated across a semi-permeable membrane, inversely proportional to the concentration of solutes. This process is crucial in many biological systems for maintaining the balance of solutes and water across cell membranes, allowing for proper cell function and homeostasis.
