Can microorganisms be seen by our nacked eye? If not,how çan they be seen?

No, microorganisms cannot be seen by the naked eye as they are too small. They are typically measured in micrometers (one millionth of a meter) or nanometers (one billionth of a meter). To see microorganisms, we need to use microscopes. Microscopes magnify the size of the microorganisms, allowing us to observe and study them in detail. There are different types of microscopes, such as light microscopes, electron microscopes, and fluorescence microscopes, each with varying levels of magnification and resolution. These instruments enable scientists to visualize and study the structure, behavior, and interactions of microorganisms.
