Chapter 19, Problem 1TQ
Summary Introduction
To review:
The approaches that can be used to the discover unknown deeply branching groups of archaea and the strengths and limitations of the same.
Introduction:
Archaea is the third major domain of life. Initially, it was found only in extreme habitats but later it was isolated from the normal habitats such as soils and oceans. The archaea are majorly divided into three phyla, namely Crenarchaeota, Thaumarchaeota, and Euryarchaeota. It is difficult to study the archaeal genomics as most of them are difficult to culture.

Give the most currently used methods in the identification and classification of archaea.
What are the promises and future uses of research in archaea?
If you visit a lake in the middle of the Amazon and take water samples to analyze under a microscope from a nearby university that has good instrumentation and there you detect microorganisms that are not visible to the naked eye. What studies would you do to determine if they are bacteria, archaea, fungi or protozoa? Explain each type of analysis and how would you rule out members of each group?

- If your instructor gave you a culture containing one species of a microorganism, how would you be able to tell whether it was an archaean, a bacterium, a fungus, or a protist? Identify and explain characteristics you could use that would allow you to distinguish amongst these types of microorganisms. Assume that you would have available any equipment or technologies needed to identify each organism. TTTT Paragraph v Arial v 3 (12pt) T 只i8公 EST T, - fr Mashups 囲 圈 田 图□mMTML cssarrow_forward. This flowchart helps distinguish among organisms by asking questions that have one of two possible answers. As a result, this flowchart can also be called a dichotomous key (from Greek dikho- 'in two' + temnein 'to cut'). Complete the flowchart by properly placing these genera: Bacillus, Corynebacterium, Escherichia, Mycobacterium, Neisseria, and Staphylococcus. You may need to look up additional information about these genera.

A) Hundreds of individuals of a species have been observed and all are photosynthetic; therefore, the species is photosynthetic. B) These organisms live in sunny regions. Therefore, they are using photosynthesis. C) If protists are all single-celled, then they are incapable of aggregating. D) If two species are members of the same genus, they are more alike than each of them could be to a different genus.arrow_forward
