Since a virus is far smaller than a typical cell (much smaller than a prokaryote) a virus cannot be seen by a regular microscope. To see a virus, you should get an electron microscope.
AIDS is the disease caused by the virus called HIV. It can not be seen under a light microscope (as one in the class lab) but you must use an electron microscope as they are very tiny.
None can. They have to be seen using a electron microscope.
The first object to be seen under the microscope is believed to be a simple microorganism called a tardigrade or a water bear. These tiny, resilient creatures are found in water and are commonly used in scientific research.
Cork cells from plants were first observed under a microscope by Robert Hooke.

A virus is the smallest because you can see a freckle with naked eye and you can see a skin cell under ordinary light microcope but viruses are ultramicroscopic and cannot be seen under light microcope. Instead a virus can only be seen under high resolution electron microscope.
SARS is a virus, requiring an electron microscope to be seen.
The chromatids can first be seen under a light microscope during the metaphase stage of mitosis, when they line up along the cell's equator.
only under an electron microscope wiki it
Yes, human eggs can be seen under a microscope.
Yes. They are too small to be seen with even the best optical microscopes.
