concentration of solutes. The potato cell has 3% of dissolved materials. Hypertonic is when the solution has more dissolved materials outside the cell than inside. The cell will lose water this way and shrink. The potatoes in the 5% salt solution will shrink. Hypotonic is when there is less solute dissolved materials inside the cell. The cell will gain water and get bigger. The potatoes in 1% salt solution will get bigger. Isotonic is when the solution has equal amounts of solute inside and outside the

molecules is higher in potato cells‚ the cytoplasm of the cell is hypertonic. The water molecule will flow from higher concentration to lower concentration‚ so that they get out of potato cells through osmosis. The plasma membrane of plant cell will collapse as the water inside the cell become less and less‚ that cause plasmolysis and the cell become flaccid. 2.

other and how a plastic bag works similar to a membrane in certain situations. Introduction: I know prior to doing this experiment that iodine mixed with starch creates a dark color and that most objects‚ organic and inorganic‚ naturally experience isotonic reactions. Hypothesis: I think that the potato will absorb more starch than the sweet potato and they will both absorb relatively similar amounts of water. Procedure: Variables: Controlled- water and size of potatoes. Manipulated variables- potatoes

“Is Starch Permeable in Cells? Abstract This report presents the weights of 3 samples of water with various amounts of solute after the use of osmosis. Three different tests were performed‚ each with a beaker of water containing varying amounts of starch from 30% concentration (12.5 grams of water) to 15% concentration (9.5 grams of water)‚ and then 0% (10.5 grams of water). To start this experiment‚ we put water into a make-shift dialysis tube‚ a type of semi-permeable membrane tubing made

osmolality and the term tonicity referrers to the osmolality of a solution. The cells in the body are exposed to three different solutions classified as isotonic‚ hypotonic‚ and hypertonic. Isotonic solutions have the same osmolality as body fluids. They do not change the size or shape of the cells‚ leaving them in a balanced state. Examples of isotonic fluids include 0.9% saline‚ Lactated Ringers (LR)‚ D5W‚ 0.225% saline‚ D5/0.225%‚ Whole Blood‚ and Packed Red Blood Cells. 5% Dextrose‚ Normal Saline

solutions are isotonic. This means that the solutions have the same concentration of solutes. If two solutions differ in the concentration of solutes that each has‚ the one with more solute is hypertonic. The solution that has less solute is hypotonic Apparatus: Experiment 1: Diffusion 1.
