Title The Unseen World Introduction Throughout the environment, a vast amount of organisms called microbes thrive. Microbes refer to the microscopically visible organisms like some bacteria, fungi, archaea, or protists. Microbes can be either unicellular or multicellular and some can even be seen with the naked eye. Bacteria and archaea, both unicellular, have evolved before eukaryotes and are the most abundant groups of organisms on earth. Because they evolved before eukaryotes, they provided the key elements that lead to the evolution of simple organisms into more complex ones in past. These elements carbon, oxygen, nitrogen, and sulfur are cycled by the bacteria and archaea and presented to the ecosystem, which are vital to both plants and animals. Fungi and protists belong to domain Eukarya. Eukarya refers to the domain of eukaryotes where a nucleus, Golgi apparatus, and mitochondria exist, even in unicellular Eukarya. Protists are mostly microscopic but some such as slime molds are visible to the naked eye. Fungi, unlike other microbes, get their food through the absorption of nutrients from either dead organisms or living ones. They reproduce by spores, which travel through water and air. Although pathogens among microbes exist, microbes are helpful to humans. Early exposure to microbes can help our immune system and we will eventually live healthier lives. The purpose of this lab is to identify the microorganisms in our environment and learn certain microscopy techniques. Having done the appropriate procedures on growing the microorganisms, depending on the location of my sampled area, I believe that the microorganisms’ abundance varies by the amount of contact the sampling area receives from humans. My hypothesis is based on the sampling of my right hand and the door knob of the classroom. I hypothesize that the sampled door knob, known to have high contact with humans, will have a higher concentration of
