    both sides) Red blood cells are bound by a membrane which allows water to pass through while generally restricting the solutes. This process, called osmosis, causes cells to shrink due to loss of water when placed in hypertonic solution. On the other hand, red blood cells absorb water (called endosmosis)...

    Random walk of small particles in suspension in a fluid was discovered in 1827 by Robert Brown. The theory of the Brownian motion and the atomistic backgrounds of diffusion were developed by Albert Einstein. Now, the concept of diffusion is widely used in science: in physics, chemistry and biology, in sociology...

  • Osmosis

    Osmosis is the movement of water through a plasma membrane from a region of low solute concentration to a region of high concentration. It is a type of diffusion. Osmosis is passive transport, meaning it does not require energy to be applied. Osmosis is essential in biological systems, as biological...
