movement of water through a differentially permeable membrane from a region of high concentration (of water molecules) to a region of lower concentration (of water molecules). We define 3 types of solutions based upon osmotic activity. In an isotonic solution‚ the solute concentration is the same on both sides of the membrane so there is no net movement of water. ( See Figure 1) In a hypotonic solution‚ solute concentration is higher inside the cell than outside. So water moves

hypertonic‚ and isotonic. Hypotonic tonicity is when the tonicity of a cell is greater than that of the surrounding liquid. In a Hypotonic solution water will flow into the cell‚ causing it to swell up like a balloon. (a&p book) Hypertonic is when the tonicity of the cell is lower than that of a surrounding liquid. In a hypertonic solution a cell will lose water by osmosis and as it does‚ the cell shrivels and dehydrates because there is higher concentration outside the cell. Isotonic is when the tonicity

Some authors have reported three types of dehydration based on serum sodium levels : hypotonic or hyponatremic‚ hypertonic or hypernatremic‚ and isotonic or isometric. Indeed‚ in humans‚ it has been commonly thought that the most commonly

get bigger. Isotonic is when the solution has equal amounts of solute inside and outside the cell. These are all different types of concentrations of solutions. The cell will not be affected at all. The potatoes in the 3% salt solution will have no change. If a cell is put into a hypertonic solution‚ the water will move out of the cell to balance the concentration difference. If a cell is put into a hypotonic solution‚ the water will move into the cell. If the cell is put into an isotonic solution‚

Title: Potato Osmosis Abstract: In this experiment was designed to study the effect of a concentrated solution applied to white and sweet potatoes. The solution’s impact among the potatoes were to be either hypertonic‚ hypotonic‚ or isotonic. The potatoes were first cut into fries with a fry cutter‚ and then weighed after being cut. The white and sweet potatoes’ weights ranged from .005-.015 grams. A total of 18 sugar solutions are to be made over the course of 3 trials. In each trial‚ 6 different

This is where the terms like isotonic‚ hypertonic‚ and hypotonic come into play. When cells retain their normal size and shape in isotonic solutions (same solute/water concentration as inside cells; no net osmosis)

the solutes‚ the higher the osmotic pressure. Osmotic pressure can be classified into three tonicities‚ which are Hypotonic‚ Isotonic and Hypertonic. Hypotonic is a situation when the concentration of water in cells are more than water outside the cell‚ causing water to flow into the cell until it ruptures and plasmolyse in animal cell and plant cell respectively. Isotonic is a situation where the concentration of water of cells is equal to the concentration of the water in the surrounding environment
