Methods. Steps to carry out the Elodea NaCl Concentration Experiment.
One) We depart put one of the Elodea sample leaf in petri suitcase containing no sodium Chloride, which we ordain be our retain test.
Two) We will put second leaf in petri dish containing 5% of Sodium Chloride and let put the sample in refrigerator which would be at constant 55 pointedness for 1 workweek. afterwards a week we will equalise if any difference is occured under a microscope.
Three) After checking the 5% sample, we will devote another sample that would contain 10% of NaCl and leave it for a week to show changes in its structure,after a week we will check again under microscope.
Four) After checking for any disintegration for 10% sample, we will place divergent sample at 15% NaCl and keep it for a week and indeed come back and observe .
Five) After observing all the sample, we would be able to see the difference surrounded by the dominance sample and other three samples. The sample with 15% would show more disintegration then the other deuce samples.
After we collect samples of Elodea, we will place four as well as sized test subjects in four separate Petri dishes.
separately dish will receive a different sum of sodium chloride. One dish will be our control containing no sodium chloride. The other three dishes with Elodea will receive concentrations of 5%, 10%, and 15% NaCl. The dishes will be kept in a refrigerator at 55°F for one week. This temperature was chosen because Elodea lives between 33°F and 77°F. When we begin our research, we will set up all four dishes and check them the following week. We will then use the microscope to observe and make drawings of Elodea cells to record what we nominate seen. We will then draw a conclusion somewhat our research based on our observations.
We will place place out samples of Elodea leaf inIf you want to get a full essay, order it on our website: Orderessay
