Osmosis - Isotonic, Hypotonic, and Hypertonic​ Solutions




Isotonic: Equal Water moves in and out of the cell at an equal rate. The cell remains unchanged. Hypotonic: "hypo" hippo Water moves into the cell, making it swell and get fat (like a hippo). Eventually the cell can rupture and burst (aka lyse). Hypertonic: "like a raisin" Water leaves the cell and goes out, leaving the cell shrunken, smaller and shriveled. Think about raisins. Raisins are the result of the water being removed from grapes, giving them a shrunken and shriveled appearance. The inside of all cells also contain a jelly-like substance called cytosol. Cytosol is composed of water and other molecules, including enzymes, which are proteins that speed up the cell's chemical reactions. Everything in the cell sits in the cytosol, like fruit in a Jell-o mold.
