Justify the division of prokaryotes into two kingdoms?

Answer 1

Because they don't have a nuclei. (nucleus)

Answer 2

Prokaryotes are divided into two groups, Eubacteria (bacteria) and Archaebacteria (archaea), because of some basic differences.

-They do not have the same material in their cellular walls (bacteria having peptidoglycan and archaea lacking it).

-They differ somewhat in rRNA, tRNA, membrane lipid structure, and sensitivity to antibiotics.

-Archaea often live in extreme environments and carry out unusual metabolic processes. (three main groups: extreme halophiles, methanogens, and hyperthermophiles)

*Under the 3 domain system, archaea are considered more closely related to eukaryotic cells, having split off very early in history but after splitting away from bacteria. This is still under investigation.

Answer 3

Because biologists found too many differences between the two to still classify them into a single Kingdom.

For Example :

Kingdom Archarabacteria

1. Cell wall lacks peptidoglycan.

2. DNA much closer to Eukarya than Bacteria.

3. Autotroph.

4. Some DNA has histones.

5. Growth not inhibited by antibiotics.

6. Several kinds of RNA.

7. Some have unusual lipids, and branched hydrocarbon.

8. Can live in extreme temperatures.

Kingdom Bacteria:

1. Cell wall contains peptidoglycan.

2. DNA differs greatly from the DNA of members of the Eukarya Domain.

3. Heterotroph.

4. DNA lack histones.

5. Growth inhibited if it encounters antibiotics such as Streptomycin.

6. One kind of RNA.

7. Unbranched hydrocarbon.

8. Cannot live in environments with temperatures above 100 degrees Celcius.

You can translate it into an essay, I hope. Maybe there's some other reason -- you can Google it and a lot of stuff will probably come out.

Answer 4

The division of prokaryotes into two kingdoms, Bacteria and Archaea, is justified based on genetic and biochemical differences. These differences include variations in cell wall composition, lipid and protein structures, and even the ability to survive in extreme environments. These distinctions ultimately reflect the evolutionary divergence of these two groups of prokaryotes.

Answer 5

Because they don't have a nuclei. (nucleus)

Answer 6

Molecular characteristics such as ribosomal RNA sequences

Answer 7

Monera is one
