Light microscope cannot be used. Electron microscopes should be used
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.
You cannot see mitochondrion under a microscope because scientists have recently discovered that they never existed. While it was believed that mitochondrion were used in order to help with the process of converting glucose into ATP, they discovered that they were not looking at an actual organelle, but rather an indention in the cytoplasm that performed the task. However, to see this so called "mitochondrion" structure, you would need at minimum a standard 400x objective lens on your microscope as well as some stain (preferably iodine) to enhance the image.
It is used to place an item on and put it under a microscope to view.
There there are many. Simple microscope, compound microscope, light microscope, scanning electron microscope, TEMicroscope, Dissection microscope, etc and most of them are used to see small cells that cannot be seen by the naked eye.
Algae are also eukariyotes.So they do have mitochondria.
A instrument used for viewing and observing
Electron microscope.
The Nucleus is seen through the use of an Optical Microscope and The Mitochondria is seen through an Electron Microscope.
There are a number of instruments that can be used in observation. You could use a telescope or microscope for example.
A compound microscope is enough to observe a bacterium. But as per the need of clarity & resolution ,one can use electron microscope etc.
A scanning probe microscope is used for observing, studying and measuring surfaces on a fine scale to the level of atoms and molecules. One can find more information about these on Wikipedia.

Telescopes are used for observing stars.
A yeast infection is diagnosed by looking at vaginal discharge under a microscope. Chlamydia is diagnosed via a cervical swab or urine test. If laboratory testing is used, you can't mistake one for the other.
Diatoms
A hemocytometer (or hemacytometer) is a tool used to count cells (red blood cells, sperm, yeast...) under the microscope. It gives the number of cells per volume of fluid.
