GENERAL KNOWLEDGE

Detailed explanation-1: -The device which is used to observe tiny organisms is called a microscope. As the germs are very small in size, we can’t see them with our naked eyes. So, we use a microscope to observe them.

Detailed explanation-2: -Bacteria are too small to see without the aid of a microscope. While some eucaryotes, such as protozoa, algae and yeast, can be seen at magnifications of 200X-400X, most bacteria can only be seen with 1000X magnification.

Detailed explanation-3: -If you’re interested in getting a good look at bacteria, you’re going to need a compound microscope with a high level of magnification. Most bacteria are small and hard to see, with an average size somewhere between 0.2 and 2.0 m (micrometers).

Detailed explanation-4: -There would be little to do in a microbiology laboratory without a microscope, because the objects of our attention (bacteria, fungi, and other single celled creatures) are otherwise too small to see. Microscopes are optical instruments that permit us to view the microbial world.
