Chapter 4, Problem 2VC
From chapter 1, figure 1.14. Study this figure. How would it be drawn differently if the archaea were more closely related to bacteria than to eukaryotes?

Students have asked these similar questions
Archaea are so named because
option1-their cell structure is thought to be more primitive than the cell structure
of bacteria
option2-they arose from the joining of members from the Archaea and Bacteria
Domains.
option3-many survive in extreme conditions thought to be similar to ancient earth
option4-they are thought to be the first group of prokaryotes to evolve on earth
Distinguish between the main groups of archaea and identify specific types of archaea belonging to each group
Read this passage from the lesson and answer the questions that follow.
Domains
The six-kingdom system didn't show that all four eukaryote kingdoms are more closely related to each
other than to the two bacteria kingdoms. It also didn't show that the two bacteria kingdoms are as
different from each other as they are from the eukaryote kingdoms. To show these similarities and
differences, a new taxon, called the domain, was introduced. It was defined as a taxon higher than the
kingdom.
The Three-Domain System
In 1990, a new classification system was introduced that contained three domains: Bacteria, Archaea,
and Eukarya. The Bacteria domain was formerly the Eubacteria kingdom, and the Archaea domain was
formerly the Archaebacteria kingdom. The Eukarya domain includes all four eukaryote kingdoms: plants,
animals, protists, and fungi. The three-domain system emphasizes the similarities among eukaryotes and
the differences among eukaryotes, bacteria, and archaea. By using domains, these…

The domain Bacteria already had too many organisms in its classification. The methanogens were discovered to be a complex organism, between prokaryotic bacteria and eukaryotes, thus it needed its own domain. He discovered that methanogens were too large to be classified as bacteria, but too small to be classified as Eukarya. In analyzing the rRNA of methanogens, he discovered that it was completely distinct from any other bacterial RRNA that had been studied. The DNA of methanogens was discovered to use different nucleotides than those of organisms in Eukarya or Bacteria.arrow_forward
