Abstract
Osmosis and diffusion are important processes in every living organism. The present study aims to show the importance of osmosis and diffusion in biology. In the experiment with dialysis bags A,B,C, and D, it is shown that the movement of molecules through a semi-permeable membrane is usually from an area of high solute concentration to an area of low solute concentration. Thus, the concentration gradient directs osmosis.
Introduction
We often overlook the importance of osmosis and diffusion in our every day lives. Osmosis is the movement of water through a semi-permeable membrane. Diffusion is the process in which molecules fuse together due to their kinetic energies of random motion. The movement of the molecules is usually from an area of high solute concentration to an area of low solute concentration. In order for osmosis and diffusion to occur, a semi-permeable membrane is needed between two substances. A selectively permeable membrane also known as a semi-permeable membrane, is a type of biological membrane that will only allow certain molecules or ions to pass through it by diffusion or other types of…
