A solution is a mixture in which the solute is evenly distibuted in the solvent and does not settle out. Solute particles are generally smaller than the solvent particles in this situation. A solution may be a mixture of solids, liquids, or gases, and when a solution has dissolved the maximum amount of solute that it can hold it is called saturated. Some example of solutions are salwater, brass (sopper and zinc), and air. The most important biological solution is saltwater which can conduct electricity, unlike pure water. Another type of mixture is suspension which is a mixture in which the solute will settle out over time. In this type of mixture, solute particles are generally larger than the solvent particles. Sand, water, and salad dressing are all different examples of suspension. Furthermore, the most important biological suspension is blood which is a mixture of clood cells and platelets. The final main type of mixture is colloid which is a gel-like mixture. In this case, the solute and solvent particles are generally about the same size. An example of a colloid mixture is jello, but the most important biological colloid is cytoplasm. In this lab, there isn’t any example of suspension or colloid, but there are examples of …show more content…
The first one is a hypertonic solution. A hypertonic solution has a greater concentration of solute than another solution. In this the solvent, which is the substance doing the dissolving, will move from high to low concentration and both plant and animal cells will shrink due to water loss which is called plasmolysis. Plant and animal cells are both not fond of hypertonic solutions because they don’t want to shrink and have no way of fighting against it. The second type of solution is called a hypotonic solution. Unlike a hypertonic solution, hypotonic solutions have a lower concentration of solute than another solution. In a similar manner as hypertonic solutions, the solvent(water) will move from its area of higher concentration to lower concentration. Due to excess water entering the cell, animal cells are liable to burst. When this happens, it is classified as cytolosis. Contradictingly, plants like hypotonic solutions because the extra water entering fills up the central vacuole in the cell. This gives the plant cell more strength and allows it to store water for later purposes. It doesn’t burst like animal cells because plant cells have a cell wall which is there for extra protection and in this case, it keeps the plant cell safe from bursting. The last kind of solution is called isotonic. In an isotonic situation, solutions have an equal concentration of solute due to water diffusing at
