Introduction In this science lab experiment we are astir(predicate) to perform, we final cause to predominate out how a onion tissue layer reacts to several(predicate) solution ( peeing, salt peeing, vinegar). We plan to tell how the membrane lead react to the three different solutions in this lab report. By doing that we leave behind write notes and draw what we see in the experiment. Hypothesis I believe the onion cells in the membrane will be by being selectively permeable by permit some molecules spin through. I think it will let pure water molecules pass through. While the salt water molecules, (the membrane) will let some pass. While the vinegar will not pass at all. We are going to win the process of diffusion however for the vinegar. Materials Paper Pencil Microscope Microscope slide Sample (onion) intention lens of the eye (x 10) Cover slip Salt water Vinegar (balsamic) 2 eye drop (water) Procedure 1.We started off by happen the microscope by the arm 2.Put it on the counter 3.Plugged it in the retail store 4.Turned the microscope on 5.We got the standards (salt water, water, vinegar, onion) 6.We put the onion on the stage 7.Drew the cells of the onion 8.Added 2 drop of water to the onion 9.Waited about a 1min 10.Drew the cells of the onion with water 11.Added a defraud of salt to the onion 12.Waited 30 seconds 13.Drew the cells of the onion with salt water 14.

Added vinegar(balsamic) 15.Waited 1 min 16.Drew the cells 17.Turned off, unplugged, and put the microscope away 18.Cleaned our materials Data record Discussion 7. No, it! did not support our hypothesis because the cells did not let the solution pass through instead of allow it pass. It obstruct them and collected on the edge of the cells. The vinegar changed the cells solely and the color. 8.Yes. It was beautiful test because everybody who did the lab report had equal part and the very(prenominal) objective so when we plunder compare our results we can find out what to do right when we do something...If you unavoidableness to get a full essay, order it on our website: OrderCustomPaper.com
