bags 2‚ 3‚ and 4 are hypertonic to the water inside the beaker. Adversely‚ the water inside the beaker is hypotonic to the sucrose inside the bag. Another example to this would be swimming in the ocean (salt water) where the ocean’s water is hypertonic (lower water concentration) and the human body is hypotonic (higher water concentration)‚ causing the water inside the human body to move from its high concentration to the ocean’s low concentration. Bag 1 represents an isotonic solution‚ where the

To study the effects of hypotonic‚ hypertonic‚ and isotonic solutions on plant and animal cells. Experiment 1 : Introduction : The purpose of doing this experiment is to investigate the effects of hypotonic‚ hypertonic‚ and isotonic solutions on plant cell. Particularly in this experiment we use onion cells. Tissue from an onion is a good first exercise in using the microscope

the solution is hypotonic‚ and water will move from the solution into the cell. If the surrounding solution has a higher concentration of dissolved molecules than the cell‚ the solution is hypertonic. In that case‚ water will move from the cell out into the surrounding solution. An isotonic solution is when the concentration of dissolved molecules is the same inside and outside the cell‚ and there is no net movement of water across the membrane. When cells are placed in a hypertonic solution‚ water

that the mass of the potato disks will increase after they have been incubated in a hypertonic solution. The mass of the potato disks will decrease after they have been incubated in a hypertonic solution. After the results have been gathered‚ appropriate estimations can then be made as to what the osmotic concentrations of the potato tuber cells are. Osmotic concentrations will either be hypertonic‚ hypotonic or isotonic depending on the results of mass change of the potato tubers. Results: Sucrose

of solute in a solvent. The higher the solute in solvent‚ then there will be a higher rate of osmosis through the diffusion gradient forming a hypertonic or hypotonic solution. Solvent with equal or no solute forms an isotonic solution. Materials: Distilled water‚ sucrose‚ dialysis tubing‚ string‚ 250 ml beaker. Procedure: To demonstrate and isotonic solution we needed 3 inches of dialysis tubing. We tied off one end of the dialysis tubing to create a bag‚ filled it with distilled water‚ and

There are 3 types of Tonicity: hypotonic‚ 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

Diffusion and Osmosis Using “Deshelled” Chicken Eggs Introduction In order for a cell to survive and function‚ it must maintain an internal steady state of environment in the midst of an ever-changing external environment. This steadiness is provided by the regulation of the movement of materials across its plasma membrane. Since not all substances penetrate the membrane equally well‚ the membrane is said to be differentially permeable. (IS) Diffusion is the tendency of molecules

diffusion. Diffusion is when molecules move from an area of higher concentration to an area of higher concentration. The three types of concentrations are hypotonic‚ hypertonic‚ and isotonic. When in comparison to another solution‚ a hypertonic solution has a lower concentration‚ a hypertonic solution has a higher concentration‚ and an isotonic is when the two solutions have an equal concentration. The experiment tested the relationship between the concentration of an egg and solutions of different
