Archaea are usually found in what kind of environments? How does this support Woese’s hypothesis for three domains of life? What does this likely say about early evolution on Earth? 7.) Archaea – no established pathogens? How does this support Woese’s hypothesis as well? 8.) Know and understand the terms: minimal medium; defined medium; undefined

known to have an independent evolutionary history. They didn’t rise up in similar conditions like bacteria and eukaryotes. Because of this they placed as a separate domain in the three-domain system‚ that divides cellular life forms into bacteria‚ archaea‚ and eukaryote domains. Also their biochemistry is different where they have a reliance on ether lipids in their cell membranes. The chemical makeup of Archea is one of the main differences why it is separated from other prokaryotes. Many forms

they are not the same so that makes them different. Since there are so many organisms‚ the organisms are separated into those two broad categories. Prokaryotes are nearly always a unicellular organisms. An example of a Prokaryote is bacteria and archaea . Prokaryotes do not contain a nucleus or a membrane that should surround the nucleus. They have a cell wall that is chemically complexed. Prokaryotes do not contain a mitchocondria. They contain two protein building blocks which is known as flagella

Gram Staining Introduction Prokaryotes are a large group of organisms with no membrane bound organelles. They consist of two domains: Archaea and Bacteria. These organisms are only found in extreme environments such as volcanoes. Prokaryotes are still being researched and are a very diverse group. In this lab we focused on trying to identify if the bacteria found had a lot of peptidoglycan by gram staining. Testing this could be done by using a Petri dish full of agar and testing different bacteria

of prokaryotic and eukaryotic cells and by exploring the process of endosymbiosos‚ one can gain further insight into the diversity of cells. One distinct difference between these cells is prokaryotic cells can be classified as either bacteria or archaea while eukaryotic cells make up all other forms of life including plants and animals. This distinction arises from the fact that prokaryotic cells are simple‚ small‚ and mostly unicellular whereas eukaryotic cells are more complex‚ big‚ and generally

many membrane-enclosed organelles. Biological domains further differentiate between kinds of cells. There are three major biological domains‚ two of which are classified for prokaryotes and the other for eukaryotes. They are Domain Bacteria‚ Domain Archaea‚ and Domain Eukarya. Evolution is also a major theme in biology. Evolution is the concept of life evolving over the course of time. Charles Darwin is responsible for the concept of evolution through natural selection. His idea of natural selection
