Introduction In this science lab experiment we are close to perform, we final cause to key out out how a onion plant tissue layer reacts to several(predicate) solution ( peeing, salt wet, vinegar). We plan to put on 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(prenominal) molecules feed through. I think it will allow 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 save for the vinegar. Materials Paper Pencil Microscope Microscope slide Sample (onion) intention electron lens (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 going 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 corpuscle 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 recording 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 jam them and collected on the edge of the cells. The vinegar changed the cells solely and the color. 8.Yes. It was decent test because everybody who did the lab report had equal part and the resembling obj ective so when we plunder compare our resul! ts 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
