What does an onion cell look like after adding a salt solution NaCl?
This depends on the nature of the NaCl solution...If it is a Hyper-tonic solution (More concentrated solution than onion cells), water will move by osmosis down it's concentration gradient, from a region of less negative water potential (high Ψ) in the onion cell, to a region of more negative water potential (low Ψ) in the solution through a selectively/partially permeable membrane;so the onion cell will be plasmolysed and will look "flaccid" (vacuole gets smaller and shrinks).The vice versa happens with a Hypo-tonic (less concentrated solution than onion cell) NaCl solution;The onion cell will then look "turgid" (has a large vacuole exerting a pressure on the cytoplasm and pushing it towards the cell's cellwall to make it "tensed".
What happens to an onion cell when placed in vinegar?
Vinegar is an acid that will break down the cell wall of the, onion cell. This could potentially break down the entire cell itself. This is why the cell will appear to have holes in it.
Does an onion cell have membrane?
Yes, an onion is a plant and plants have cell membranes and cell walls
Where is the red pigment of a red onion?
cell membrane
Why do you use iodine solution during the preparation of slide of onion peel?
So that you can observe different characteristics of the cell clearer such as the nucleus, vacuoles or other membrane bound organelles.
What would happen to red onion cell if sucrose solution added?
In a hypotonic solution like distilled water the onion cell would "swell up" and the cytoplasm expands and water diffuses into the cell
Is the onion membrane 2 layers thick?
it is 7 layers
Do onion cell have a cell membrane?
no they have cell walls because only animal cells have cell membrains
What happens to onion cells in freshwater?
they will disintegrate and soon the onion will peel and the onion part will BE NO MORE
What is the purpose of ice-cold ethanol?
In an experiment to extract DNA from something like an onion or strawberry, the last step is to slowly pour ice cold ethanol into the test tube. This causes the DNA to precipitate out of the solution and white stringy material appears a the boundary of the ethanol and prepared DNA solution. The reason why it happen is because ethanol solution break down the nuclear membrane and cell membrane.
How will the cells in an onion membrane respond to pure water?
nothing will happen
Does the onion cell and green leaf also have cell membrane?
Yes.
