Question

Select all that apply. You can identify or classify archaea and eubacteria by _____.

Answer 1

If you wanted to try and identify or classify archaea or eubacteria, you would study their habitat, study their genetic make-up, study their shape and arrangement, conduct Gram staining, study how they gain energy and nutrients and study how they move. Archaea and eubacteria are genetically different; Archaea have more complex RNA polymerases that contain multiple polypeptides while eubacteria have simple RNA polymerases that contain four polypeptides. Archaea cell walls do not contain peptidoglycan while almost all bacteria cell walls contain peptidoglycan.

Answer 2

Archaea and eubacteria are both prokaryotes that lack organelles. They are a unicellular organisms that has thick cell walls and reproduce asexually through binary fission.
In order to determine whether an organism is archaea or and eubacteria you must consider the following characteristics or factors:
1. habitat
2. their means of existence
3. genetic makeup
3. the shape of their cells
4. arrangement/ cell organization
5. through gram staining
6. how they gain nutrients
7. how they move
