Osmosis in potato cells 1

Which way did the water move?

Osmosis potato experiment salt solution results

Potatoes are full of both water and starch, and will gain water when immersed in watery solutions. Water molecules have mass and so the decreased number of water molecules results in decreased mass. Make solutions of saline in three different concentrations, 20 percent, 0. Plant cells react to osmosis by hypertonic, isotonic and hypotonic. Mass weigh each to the nearest 0. Osmosis Lab Introduction: Human blood, at 0. I will use these values to find the solute potential by using the calibration graph. Introduction To carry out my experiment, I will place the potato tubes into a solution containing part sucrose and part water. Make one salt water solution, one sugar water solution, and for the third solution, simply use tap water.

It occurs in both animals and plants cells. You won't be able to tell the salinity just by looking. Simply, will the effect of the action of osmosis be affected by the concentration of the solution?

Potato osmosis experiment results

I used salt solution in three different concentrates: 0. Observe each strip by feeling it, noting whether it is turgid or flaccid. Just enter the water volume of your container and the percentage of salt you want and it will tell you how many grams of salt to add. Make one salt water solution, one sugar water solution, and for the third solution, simply use tap water. In order to find the best way to do this experiment I am going to do a preliminary test first. Which way did the water move? Conversely, they will lose water when in concentrated solutions, such as those containing a great deal of starch. Osmosis is the diffusion of water.

After immersion, weigh each group again and have your students calculate the changes in the potato masses. Results: 1.

Start the timer. The initial mass of potato is noted before being placed in the solution.
