EVERYDAY SCIENCE

Detailed explanation-1: -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. This requires a 100X oil immersion objective and 10X eyepieces..

Detailed explanation-2: -If you want to see a bacterium, you need a really powerful magnifying glass. In other words, you need a microscope. The Dutchman Antoni van Leeuwenhoek (1632-1723) was the first person to make high-quality microscopes. Lenses are an important part of a microscope.

Detailed explanation-3: -At 1000x magnification you will be able to see 0.180mm, or 180 microns.

Detailed explanation-4: -Bacterial cells are around 1 micron in size, which makes them invisible to the naked eye. Fluorescence microscopy allows different parts and aspects of bacteria to be visualized-including nuclei, cell membrane, organelles, and even specific proteins.

Detailed explanation-5: -Answer and Explanation: Bacteria are small, but they are still large enough that most can be seen with a compound optical microscope. If increased magnification is needed, an electron microscope can be used.
