Why do you use the onion for cell sample and not the leaf?
An onion is easy to peel to 1 layer of cells, and with a light microscope you cant see the individual cells in a leaf. Also the cell obtained from the bulb of onion is colorless, hence it can be easly stained with different dyes to study the cell organells under the microscope.
Parts of an onion skin cell that you can not see?
the chloroplast
What does effect iodine have on the onion cells?
iodine stains the onion cells so that you can see the cell better. you can see the nuclei and cytoplasm.
What structures were you able to see in the onion cell?
The Human cell and Onion cell have Nucleus
What cell structures can be seen in a stain onion cell?
The structure that is seen is the cell wall. This keeps the shape of the cell and is only found in plant cells. The organelles that can be see in a stained onion cells all depends on your microscope. Under a x400 light microscope we could see the cell wall, cell membrane, nucleus and cytoplasm,
Why do your eyes burn when you peel an onion?
I am pretty sure it is just the juices when they get into ur eyes likes an orange when u get the juice in ur eyes it burns. That is correct. When you peel the layers of an onion, droplets of onion juice float into the air. They are usually too small to see, and not strong enough to burn the skin, but eyes are more sensitive.
Why is iodine used when observing onion cells?
AnswerIodine was used to stain onion epidermal cells so you could see the cells more clearly and examine them. Naturally, the cell parts are difficult to see because they are clear.You put iodine on onion cells in order to make parts of the cell which were translucent, more visible. This is because iodine stains starch present in the onion cell.
Why onion is used to see the structure of a plant cell?
because it has plant cells
Can any one see the cell wall of onion through the microscope?
Yes.
Why you use iodine in onion?
Iodine stains the onion so it is easier to see the cellular features, such as the nucleus, cell wall, and cytoplasm.
What would happen if you added three drops of iodine to an onion?
I did this experiment and after a while the onion cell became incredibly easier to see.
Can you clearly see as a structure the cell membrane in check cells and the cell wall inthe onion skin clls?
Yes. If viewed under even a simple light microscope, the cell structure of a cheek cell and the cell walls of an onion cell can clearly be seen.
