An osmosis coursework on the practical applications of osmosis could help other students understand how the principle of osmosis plays an important role is solving many problems that exist in the transportation of water. Basically, osmosis is the movement of molecules of liquids from an area of high concentration to an area of low concentration. This is due to the passage of liquid (water) though a semi permeable membrane, which allows certain molecules to pass through by diffusion or the process of spreading and transmitting across the membrane. Certain cell membranes are completely permeable to water. An essay on cell structure could elaborate further on how osmosis takes place.
To understand how osmosis works a little better, let us define semi-permeable membranes. These are thin layers of material that allow small molecules like water, oxygen, carbon dioxide, and amino acids to pass through. They do not allow larger molecules like starch or protein to pass through. So a custom essay would verify that a region of high concentration would be a solution of mostly water and would contain very little proteins or starch. Similarly, a region of low concentration would be a concentrated solution of proteins with less water. When an animal of plant cell is put into a vessel of water, it could therefore absorb more water if the cell has a low water concentration and vice versa.
Animal cells have a different sort of problem due to osmosis. They do not have hard outer cells that create hydrostatic pressure. So animals that are on the land or in the sea need to preserve water and those living in river water areas need to shed water. Basically, animals adjust to liquids that have the same osmotic strength as their cytoplasm. An essay guide would compare this phenomenon to the kidneys playing an important role in maintaining the level of water and salt in animals and humans. Reverse osmosis is another important phenomenon which has found practical applications that can help mankind. Water desalination is one such example where sea water is forced through semi-permeable membranes that prevent salts from passing though and allowing water to pass which is then processed for human consumption. Osmosis coursework can really attempt to introduce many such technological breakthroughs using osmosis.
