Small rectangular cells with small spherical balls inside.
Predicting the function of onion cells depends on what type of cells you observed. Root cells allow the surface to absorb more water and nutrients while bulb cells form starch for energy.

This is so we are easily able to see and differentiate the organelles when examining the cell under a microscope.
Onion epidermal cells occur mitosis (nuclear division) and cytokinesis(cell division). Interphase cell typically have one or more number of nuclei, so a few nuclei do not appear next to a cell wall.
Ron is observing an onion cell on a slide under a microscope. He sees chromatids being pulled to opposite ends of the cell. Which phase is he seeing?
It is not possible to see organelles with a compound light microscope because some organelles are to small to be seen with the low magnification of the light microscope. If they can not be seen through the compound microscope they are normally looked at through the electron microscopes (transmission electron microscope {TEM} or scanning electron microscope {SEM}).
We looked at the cell's organelles under the microscope.
4.Nucleus
The organelles in a cheek cell that are not visible under a light microscope are the ribosomes. These organelles are responsible for protein synthesis.
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,

The nucleus, and cell wall. Other organelles would be too small to see in a regular classroom microscope.

becuse of the lodine solution
Yes, sometimes there will be green portions of the onion. If you look at those cells under the microscope, you will see chloroplasts.

When observing an onion cell under the microscope, it appear to be long an oval in shape. Staining the cell will make the chromosomes attain a deep purple color.
The function of the onion cell is to store energy and water for the onion, which will be used later on.
