Osmosis term paper

Diffusion is the process in which particles move from an area of high concentration to an area of low concentration in order to evenly spread out.

Experimentation is necessary to determine which membranes permit selective flow, or osmosis, because not all membranes act in this way. Many membranes allow all or none of the constituents of a solution to pass through; only a few allow a selective flow.

In a classic demonstration of osmosis, a vertical tube containing a solution of sugar, with its lower end closed off by a semi-permeable membrane, is placed in a container of water.

As the water passes through the membrane into the tube, the level of sugar solution in the tube visibly rises. A semi-permeable membrane that may be used for such a demonstration is the membrane found just inside the shell of an egg, that is, the film that keeps the white of the egg from direct contact with the shell.

In this demonstration, the water moves in both directions through the membrane; the flow is greater from the vessel of pure water, however, because the concentration of water is greater there, that is, fewer dissolved substances exist in this solution than in the sugar solution.

The level of liquid in the tube of sugar solution will eventually rise until the flow of water from the tube of sugar solution, under the influence of hydrostatic pressure, equals the flow of water into the tube. The hydrostatic pressure establishing this equality of flow is called osmotic pressure.

A variety of physical and chemical principles is involved in the phenomenon of osmosis in animals and plants Essays, term papers, research papers related:Introduction Osmosis is the movement of water from a region of higher concentration (hypertonic) to a region of lower concentration (hypotonic solution) through a cell membrane or other semi-permeable membrane until an equilibrium is reached.

Excerpt from Term Paper: Diffusion and Osmosis Experiment Lab Report The core purpose of the first experiment conducted in the lab was to study the principle of diffusion. The experiment aimed at analyzing the movement of molecules from a region of higher concentration towards lower concentration. With osmosis, there is a membrane which does not allow dissolved material to pass though it but only water (selectively permeable) Osmosis is the movement of water molecules from a weak solution to a strong solution/5(3). Osmosis is the movement of the water molecules across a partially permeable from a region of high water concentration to a region of low water concentration. Osmosis is a special case of diffusion The biochemical process in living cells always takes place in .

It is a special case of diffusion called “ passive transport “ which means no energy is required. The tools you need to write a quality essay or term paper; Saved Essays. You Have Not Saved Any Essays.

Definition of Osmosis: Osmosis can be defined as the passage of water molecules from a region of high water potential, to a region of lower water potential, through a partially permeable membrane.
