Prokaryotes make up microorganisms (microscopic organisms without a nucleus or special organelles or structures), and present strong toxins to us eukaryotes (organisms with a nucleus and special organelles). The naked eye observes macroscopic organisms (large creatures) such as animals and plants, but only microscopes can perceive microorganisms (microscopic organisms). Today, individuals use the compound microscope for most occasions. A Microscope enables individuals to examine up to 1000x magnification, so up to 1000x the normal vision of a human.

Microbes become inhaled while breathing and crawl off macro-organisms to adhere onto everything. Like humans, microbes include parts of the life cycle. Many humans may not have much knowledge about microbes, since some don’t wash their hands, and some allow children to play in dirt or mud. Some people don’t wash their sheets often, and some don’t shower or brush their teeth as required. This shows the lack of knowledge that most individuals have about microbes. Microbes exist everywhere, yet many individuals still require hygiene education.
