How to remove water from a cell?

Question

It's for biology

Answer 1

put in salt water!!! Osmosis will cause the cell to lose water. We do this in class under a microscope using eolodea. It cause the cell membrane to move away from the cell wall and gather around the nucleus.

Answer 2

put the cell in a salt water solution.

When a plant cell is placed in a hypertonic solution, the water in the cells moves to an area higher in solute concentration, and the cell shrinks and so becomes flaccid [pron. flaxid]. (This means the cell has become plasmolysed - the cell membrane has completely left the cell wall due to lack of water pressure on it (the opposite of turgid)).

Osmosis can also be seen very effectively when potato slices are added to a high concentration of salt solution. The water from inside the potato moves to the salt solution, causing the potato to shrink and to lose its 'turgor pressure'. The more concentrated the salt solution, the bigger the difference in size and weight of the potato chip.

Answer 3

Add a compound to the solution outside of the cell the that the water in the cell moves out trying to dilute the concentration outside of the cell.

Answer 4

The easiest way is to put the cell in an enviornment that has no water in it. By diffusion, the water will be transported out of the cell. You could also dry it out, like w/ a heater or burner or something.

Answer 5

Mixed with hypotonic solution and use dry centrifugation

Answer 6

place it in a hypotonic solutuion

Answer 7

you cant...lol
