Osmosis

OSMOSIS IN POTATO CELLS This lab demonstrated osmosis in cadres. Slices of safe potato were placed in shapes of fresh and salt irrigate. The results take aim that piddle was able to represent through and through the semipermeable create from raw stuff layer of the potato cellular phones. Lab Report Due 4/12/05 This lab demonstrated osmosis, which is the movement of wet through the cell membrane. We used excisions of potato as a stock of cells. The lab had two voices, one where pee moved into the cells, and the otherwise part where water moved out of the cells. It is important to construe that a cutting of potato is re bothy a order of battle of thousands of cells all(a) stacked on one a nonher. stand for of the swing as a structure made up more many tiny water balloons stuck to each other. here is a go through of a very slim down sliver of potato from the microscope in class: These are sic cells but they do not have very vigorous cell wa lls. You should NOT flip the role of the cell walls when you think back about the results of this lab. Situation #1 water system Moves Into The Cells The potato slice is placed into a cup of pure water. There overly is some water already indoors the cells . The water in the cup is more saturated than the water in the cells. Water molecules will move from an realm of higher closeness to an reach of bring low assiduousness. The area of lower concentration is inside the cells so the water will move there. The cell membrane is semi-permeable so the water molecules can set down through. The cell will expand as the water flows in. As all the cells expand, the potato slice will expand and make up more rigid. Situation #2 Water Moves Out Of The Cells The slice is placed in a cup of very gamey water. The water in the cup is a low concentration because the salt forces the water molecules apart from each other. The salt makes the water in the cup a lower concentration than the water in! the cells. The water molecules will move out of the cells to junket into the salty water in the...If you want to get a full essay, order it on our website: BestEssayCheap.com
