Facultative bacteria gather mostly at the top since aerobic respiration is most efficient, but since they can survive with a lack of oxygen, they can be found throughout the culture. 4. Microaerophiles gather at the upper part of the test tube but not at the top. They require oxygen but are poisoned by high concentrations of oxygen. 5.
WebAug 26, 2024 · Life on Earth can be classified into two main categories: eukaryotes (e.g., plants, animals, fungi, amoeba) and prokaryotes (e.g., bacteria and archaea). Archaea is a domain of single-celled organisms. These microorganisms lack cell nuclei and are therefore prokaryotes. Archaea were initially classified as bacteria, receiving the name archaebacteria (in the Archaebacteria kingdom), but this term has fallen out of use. Archaeal cells have unique properties separating them from the other two dom…
