What are the similarities and differences between bacteria and archaea?

Bacteria contain fatty acids on the cell membrane, whereas archaea contain phytanyl. Explain the statement that both types, bacteria and archaea, have the same basic structures, but built from different chemical components. Both bacteria and archaea have cell membranes and they both contain a hydrophobic portion.

Are there two or three domains of life?

Summary. That Bacteria, Archaea and Eukarya (eukaryotes) represent three separate domains of Life, no one having evolved from within any other, has been taken as fact for three decades.

What are the differences between bacteria and eukarya?

The most obvious difference between eukaryotes and bacteria is that there is a membrane-bounded nucleus in eukaryotes and not in bacteria – again, for the most part: there is a bacterium with the wonderful name Gemmata obscuriglobus that is described as having a double membrane enclosing the DNA in a nucleus- like …

What three structures are possessed by all bacteria?

  • glycocalyx.
  • outer membrane.
  • cell wall.
  • cytoplasmic membrane.

What came first archaea or bacteria?

As the evolutionary story is usually told, first came the prokaryotes: the archaea and bacteria, which are often envisioned as simple bags of enzymes without an intricate structure.

What are 3 examples of Archaea?

There are three major known groups of Archaebacteria: methanogens, halophiles, and thermophiles. The methanogens are anaerobic bacteria that produce methane. They are found in sewage treatment plants, bogs, and the intestinal tracts of ruminants. Ancient methanogens are the source of natural gas.

Which is the oldest prokaryote?

The oldest known fossilized prokaryotes were laid down approximately 3.5 billion years ago, only about 1 billion years after the formation of the Earth’s crust. Eukaryotes only appear in the fossil record later, and may have formed from endosymbiosis of multiple prokaryote ancestors.

Can bacteria have cell walls?

A cell wall is a layer located outside the cell membrane found in plants, fungi, bacteria, algae, and archaea. A peptidoglycan cell wall composed of disaccharides and amino acids gives bacteria structural support. The bacterial cell wall is often a target for antibiotic treatment.
