Question

Differences between archaea and bacteria

Answer 1

Both bacteria and archaea have different Ribosomal RNAs (rRNA). Archea have three RNA polymerases like eukaryotes, but bacteria have only one. Archaea have cell walls that lack peptidoglycan and have membranes that enclose lipids with hydrocarbons rather than fatty acids (not a bilayer). These lipids in the membranes of archaea are unique and contain ether linkages between the glycerol backbones rather than ester linkages. Archaea resembles eukaryotes more than bacteria. Their ribosomes work more like eukaryotic ribosomes than bacterial ribosomes.

These two microorganisms also differ in genetic and biochemical ways. Only within the last couple of decades, archaea were recognized as a distinct domain of life. They are extremophiles, meaning they thrive in physically or geochemically extreme conditions. They have similar ecological roles as bacteria. Both of these organisms react to various antibiotics in a different way.

Answer 2

Answer:

Explanation:

Archaea and Bacteria they both are micro-organism. They both are similar in size and shape but differ in their other characteristics.

1) The cell wall of bacteria made up of Peptidoglycans (proteins & sugar) , where Archaea do not contain this compound in their cell wall.  

2) Archaea consists of three RNA, Bacteria consists of single RNA.

3) Archaea reproduce asexually by fermentation, budding pores and binary fission , where Bacteria can produce spores to stay in unfavorable condition.

4) Archaea can survive in extremely harsh environment such as Hot Springs, where Bacteria generally found in water, soil , animal, plant etc.
