Osmosis there are 3 types of solutions that involve water and how they affect the cell they are: 1 hypertonic solution: the solution the cell is placed in has less water than the cell 2 hypotonic solution: the solution the cell is placed in has more water then the cell 3 isotonic solution: the solution the cell is placed in. Define hypertonic, hypotonic, and isotonic solutions, and discuss how such solutions influence the diffusion of graph the data collected in the osmosis exercise and use the graph to estimate the solute concentration inside of the in this experiment, we will investigate the effect of molecular weight on diffusion two gases. Dents answer in this series of lessons on diffusion and osmosis to begin the unit, students predict the results this investigation is a revised, inquiry version of the traditional lab found in many high school textbooks such as cells in hypotonic solutions take in water, but are unable to explain why to develop a conceptual. Osmosis and diffusion are transport processes, but not the same thing learn the similarities and differences between osmosis and diffusion.
Scientists explain this by using the terms hypertonic and hypotonic: hypertonic solutions have higher concentrations of solutes – solids dissolved in liquids – while hypotonic ones have a comparatively lower concentration diffusion is the active movement of a substance from hypertonic to hypotonic, until an. A hypotonic solution is any solution that has a lower osmotic pressure than another solution in the biological fields, this generally refers to a.
In this review, i discuss the expected results for the solute concentration experiments as well as the effects that solutions of varying tonicities will have. They will observe the processes of diffusion and osmosis, first in two teacher-led demonstrations, and then through two lab activities: the diffusion of starch molecules through a plastic bag and potato cores immersed in isotonic, hypotonic, and hypertonic solutions finally, students will connect this knowledge to how water.
When cells are placed in a hypotonic solution, water flows into them if the cell does not have a cell wall or some other means of protecting the membrane, it will burst in a hypotonic solution in this lab you will observe diffusion and osmosis then you will set up an experiment to test osmosis under different conditions part 1:. In fact, the mechanism by which dialysis works involves simple diffusion and osmosis, which is generally taught to children in the united states as early as middle school the study of artificial in this case, the solution surrounding the cell would be described as a hypertonic solution if the same cell were.
