Alexander Fleming “discovered the existence penicillin through a combination of perceptiveness and luck” (Krogh, 2011, p. 398). While he was growing bacteria in a petri dish, he notices the appearance of a type of fungus. The contamination caught the attention of Fleming. He realizes that he had found a substance that had the power to kill bacteria. Fleming continued to grow more fungal mold and tested it on different kind of bacteria. Additionally, he tested it on healthy mice in which he obtained an adverse effect from it. Fleming figured out that there were numerous substances that can kill bacteria. However, he needed to find one that could kill bacteria in humans without causing harm. Unaware of his discovery Fleming did not produce the

Whereas, prokaryotes cannot live in harsh conditions because of their complexity. Archaea can be found in places all over the world, like hot water pools, areas with high salt concentrations, cold temperature areas, and in areas without oxygen. They can grow in areas that would kill most organisms. It has distinct domains that make them extremophiles, meaning that they can grow in more than one condition. Additionally, prokaryotes include cells that have a nucleus, which makes them eukaryotes. It includes animals, plants, protists, and fungi. Archaea also have cell walls that do not contain the peptidoglycan found in bacterial cells. It also lacks the cellulose that is found in plant cells, it also lacks the chitin that is found in fungal cells. Archaea are also structurally different from prokaryotes, the chemical structure that it contains makes it unique. Because of their ability to live in almost in condition archaea is one of the most abundant organism on the earth. They also have a larger role than bacteria in the nitrogen fixing …show more content…
It is one of the oldest life form on earth. Unlike, other life forms bacteria is a major contributor to earth ecosystem and it is also essential to human life. Its characteristics are differences from many other living life forms. One of its characteristics includes adaptability, it can be found almost anywhere, such as soil, the air, water, and on the human body. It has the ability to thrive in any environment to include extreme environmental conditions that will not hinder its growth. Because of its ability to grow in harsh conditions it is referred to as extremophiles. There are three categories of extremophiles, first, is thermophiles which makes its home in hot environments. Second, is halophiles, it live in areas with high salt concentration. Last, is anaerobes, it can live in an oxygen free environment. Another characteristic of bacteria is it diversity, it has the ability to produce its own food through photosynthesis. It also has the ability to produce food in a conventional way. Its diverse metabolism also gives it the ability to survive without oxygen and to be poisonous. The physical form of bacteria is another example of its diversity. Bacteria can be identified by the shapes in which it may assume. A round shape, a rod shape, and a spiral shape. It can be identified as cocci, bacilli, and spirochete. The different shapes allow bacteria to function in different places across the world. Bacteria
