membrane between the solvent on the other side. The water then moves through the membrane to make the solution more isotonic‚ which means that each side will have an equal amount of water to glucose ratio. With osmosis there are also processes that do not end so well in the concentrations being equal. In hypotonic solutions water flows into a low concentration area‚ in a hypertonic solution water is forced out

exact concentration of the cell which is the solvent the solution is known to be an isotonic solution. When the concentration of the solute is greater than the concentration of the solvent the solution is known to be a hypertonic solution. Finally‚ when the concentration of the solute is lower than the concentration of the solvent the solution is known to be a hypotonic solution. Therefore‚ hypertonic and hypotonic solutions aren’t at equilibrium. Variables * Independent * The change in

An investigation to find the water potential of potato and carrot tubers in a sucrose solution‚ of concentration 0.00 – 0.50Mol‚ over a 24 hour period Interpretation Written Communication C1 From our graph it can be seen that the concentration of sucrose solution is 0.18 M at 0% change in mass for the potato and 0.355 M at 0% change in mass for the carrot. I will use these values to find the solute potential by using the calibration graph. I will work out the water potential by using the

Movement of water across membranes that does NOT require cellular energy 2. Hypertonic solutions contain high concentration of solute when compared to another solution. 3. When a cell is placed in a hypertonic solution‚ what happens to the cell? shrivels 4. Play the small movie. 5. Hypotonic solutions contains a low concentration of solute when compared to another solution. 6. When a cell is placed in a hypotonic solution‚ what happens to the cell? swells 7.

in both areas are equal and no net movement will occur from one area to another. If two solutions have the same solute concentration‚ the solutions are said to be isotonic. If the solutions differ in concentration‚ the area with the higher solute concentration is hypertonic and the area with the lower solute concentration is hypotonic. Besides osmosis and diffusion‚ molecules and ions can be moved by active transport. This process includes the use of ATP (adenosine tri-phosphate) to drive

depended on the concentration of dissolved solute in the water (in this case the sucrose) and if there are a higher concentration of sucrose in the visking tubing‚ the water in the beaker will move into the visking tubing to make both solution balanced (isotonic). In order for osmosis to occur naturally‚ a semi-permeable membrane is required as a medium. A visking tubing is a semi-permeable membrane‚ therefore it will be used to act as the ‘cell’ for the experiment. This is because the phospholipid bilayer

Labset Three Worksheet 1. What is a carbohydrate profile? Why are they used as a diagnostic or identifying tool? (2) Carbohydrate profiles are specific information on the type and amount of carbohydrate that a product contains. It is used to identify and differentiate two closely related species. 2. What are the carbohydrate profiles of the organisms you tested? (2) The yeast carbohydrate profile came out with glucose and fructose positive and Mannitol negative. The staph epidermidis

From previous knowledge I know when a plant cell is put into a solution with the same concentration as the cell contents‚ this is referred to as isotonic‚ some water molecules move in and out. Due to no concentration gradient‚ no net flow. When a plant cell is placed in less concentrated solution than the contents of the cell it’s referred to as hypotonic‚ some water molecules move out of the cell but more move into the cell. The

Another objective was to understand the nuances of simple diffusion‚ facilitated diffusion‚ and active transport and to explicate the characteristics affecting the rates of diffusion. The next objective was to be able to explicate the partition coefficient and its influence on hemolysis. The final objective was to properly use a pipette (Spilios‚ 2015). Hemolysis occurred despite the red blood cells being in isotonic solution (0.3 M)
