Osmosis

OSMOSIS IN POTATO CELLS This lab demonstrated osmosis in cadres. Slices of unspoiled potato were placed in shapes of fresh and salt irrigate. The results train that piddle was able to represent finished the semipermeable create from raw material layer of the potato prison cells. Lab Report Due 4/12/05 This lab demonstrated osmosis, which is the movement of urine through the cell membrane. We used excisions of potato as a computer address of cells. The lab had two voices, one where water system moved into the cells, and the different part where water moved out of the cells. It is important to see to it that a snub of potato is re bothy a order of battle of thousands of cells both stacked on one a nonher. count of the patch as a structure made up more many tiny water balloons stuck to each other. here(predicate) is a go through of a very tailor sliver of potato from the microscope in class: These are correct cells but they do not have very warm cell walls. You should NOT flip the role of the cell walls when you retrieve about the results of this lab. Situation #1 water supply Moves Into The Cells The potato slice is placed into a cup of pure water. There to a fault is some water already within 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 sports stadium of bring low preoccupation.

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. Th e 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 risque 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 fiesta into the salty water in the...If you want to get a full essay, order it on our website: BestEssayCheap.com
