Investigating the concentration of Glucose inside Cell sap in potatoes Through Osmosis.

In the fol ruggeding essay I allow for be await into the c oncetration of glucose in the cellular telephone tire of a stump spud cell by weighing the samples of potato in the first place and aft(prenominal) soaking them in a concetrated glucose solution. I predict, that the stronger the solution of glucose, the more(prenominal) weight unit the piece of potato lead lose, and when displace in a more dilute glucose solution, the potato will gain weight. This is due to Osmosis, the movement of pee molecules from an area of proud concetration to an area of low immersion. The cell membranes are permeable to water, and so if the glucose concentration deep fell the cell is more surd than the solution its placed in, water molecules will pass through and through the cell wall to the solution, unsex the potato to gain weight. For this experiment I will be using small cylinder shaped pieces of potato, 5cm long, and cut with a cork borer to see to it the equal width fo r severally piece. I will be finding out the concentration of glucose inside the cell sap by controlling the corresponding quantitys of different glucose solution of a different concentration. I will be weighing the batch of the potato before and after placing it in the glucose solution, and measure the beat of weight gained, or lost, once soaked for on the nose ten minutes.

Equipment Stopwatch Cork Borer Ruler electronic Weighing Scales Measuring Beaker Petre Dishes I will be fashioning my test as fair as possible, by ensuring I have enough data to note down the mean(a) results. I will be doing this by placing one-third pieces of potato into each petre dish filled with the! same amount of coveted concetrated glucose solution. All three pieces must be exactly the same size, and so I will be measuring to make sure the length of... If you want to get a rich essay, order it on our website: BestEssayCheap.com
