yes they are observed by microscopes
Objects that are too small to be seen with other microscopes can be observed with an electron microscope, which uses a beam of accelerated electrons to create an image with much higher magnification and resolution than light microscopes.
Microscopes produce magnified images by using lenses to bend light rays and focus them on the specimen being observed. The magnified image is then viewed through the eyepiece or a camera. Various types of microscopes, such as compound microscopes and electron microscopes, use different methods to achieve magnification.
Light microscopes use light waves to magnify and visualize samples, while electron microscopes use a beam of electrons. Electron microscopes have much higher magnification and resolution capabilities compared to light microscopes, allowing for finer details to be observed in samples.
Two scientists who studied cells using microscopes were Robert Hooke, who in 1665 was the first to observe cells in a piece of cork, and Anton van Leeuwenhoek, who in the 1670s observed single-celled organisms through his microscopes.
The size of a cell can be measured under the microscope by micrometery and its shape is also observed by microscopes.
No I have to add that "no" might not be entirely the correct answer. Here's a wiki entry about "Atomic Force Microscopes". It also includes actual pics: http://en.wikipedia.org/wiki/Atomic_force_microscope It works very differently than the microscopes we are used to. It's a good read, check it out.
The lack of microscopes with sufficient magnification capabilities before the 1600s prevented scientists from observing cells. It wasn't until the development of the compound microscope in the 17th century that cells could be visualized.
Tiny objects can be observed using a microscope. Microscopes magnify objects to make them appear larger and allow for detailed examination of structures that may not be visible to the naked eye. There are different types of microscopes, such as light microscopes and electron microscopes, that can be used to observe tiny objects at various levels of magnification.

Resolution in microscopes refers to the ability to distinguish between two closely spaced objects as separate entities. It is determined by the numerical aperture of the lens and the wavelength of light used for imaging. The higher the resolution, the finer the details that can be observed in the sample.
That is Anton Van Leewan Hook.He observed microbes first.
Scientists using the earliest microscopes observed tiny organisms such as bacteria and protozoa for the first time. They also discovered that cells were the basic unit of living organisms, leading to the development of cell theory.
