Can you observe any chloroplast in the onion cell using microscope?
Yes, sometimes there will be green portions of the onion. If you look at those cells under the microscope, you will see chloroplasts.
Are the nuclei invisible in the onion epidermal cells?
It can seen vaguely and invisible under the microscope
What is a good substiute stainfor looking at onion root tips under a microscope?
Iodine, its yellow and stains cells very well for viewing under a microscope.
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.
Is cytoplasm visible in onion cells?
it is like a rectangular shape .nuclear nuclear can be seen under microscope
How do cells of the onion specimen appear under the microscope?
The cells of the onion appeared to be crooked.
What shape are onion cells?
Like a misshaped box. It is grey under a microscope.
What effect did staining the onion cells have on their appearance under the microscope?

What parts of the onion cells?
Those that you can see under the microscope are the cell wall, nucleus, nucleolus, and cytoplasm.

Predict the function of the onion cells that you observed under the microscope. What prominent cell structures would justify your prediction?
The function of the onion cell is to store energy and water for the onion, which will be used later on.
How did the iodine affect the image of the onion cell?
Iodine dyes cells a purple color. This enables things to be seen easier under a microscope.
How did the solution affect the image of the onion cell?
Iodine dyes cells a purple color. This enables things to be seen easier under a microscope.
