Osmosis and Diffusion in Potato Cells

The Effects of NaCl and DI irrigate on Potato Cells Abstract: The go over we conducted gave the result that when a white tater vine has contact with a flavour solvent, the cells will start to shrink. We did this by cutting up slices of potato and weighed them and recorded their initial weights. We used deionized water and three several(predicate) concentrations of sodium chloride solutions; 10% NaCl, 15% NaCl, and 20% NaCl. We than placed each potato slice in block out tubes with their designated solutions. We let them steal for 20 minutes than we removed them from the test tubes. Next we measured their new weights and recorded them. They were; 10% NaCl decrease by 4%, 15% NaCl reduced by 8%, and 20% NaCl decreased by 12.5%.The results showed us the conclusion that the potatoes were hypertonic to the deionized water and were hypotonic to the sodium chloride solutions. Introduction: The objective of this prove is to detect scattering and osmosis in potato cel ls in 3 solutions. Diffusion is the unwritten spread of molecules from an area of high concentration to an area of spell 1 concentration. Osmosis is a type of diffusion involving water. The results will every be hypertonic or hypotonic. Hypertonic means that the solution is much than give than water. Hypotonic means less salute and more water.

For this lab, we erect apply these principles to plant cells. The plant cells turn over a semi permeable membrane so they can palpate osmosis and diffusion as discussed earlier. When it comes to the potato cells, added with NaCl ( sodium chloride) it will survive a reaction ch anging the form of the cells. The hypothesis! of this experiment goes as follows, If we place potato cells in a salt solution, therefore the cells will shrink. They will shrink because when the salt is added the water in the potato, where there is high concentration, will move to the away(p) of the potato where there is low concentration. Methods: When we started the experiment we took 6 test tubes and fill up half with NaCl and the...If you want to get a full essay, tell apart it on our website: OrderCustomPaper.com
