Question

Why might it be more useful to classify Bacteria and Archaea based on their morphology rather than solely on their phylogeny?

A. Both domains are capable of sharing segments of DNA with unrelated organisms which makes genetic classification difficult.
B. Classifying them by shape is more practical since each domain has its own unique and distinctive shapes.
C. Morphological distinctions are easier to represent on paper than phylogenetic relationships.
D. The genetic make-up of both domains is so similar that it makes it difficult to make genetic distinctions between species.

Answer 1

Archea are primitive, they were first on our planet and they are present nowadays with their primitive characters. They have the unique features of being able to live in harsh areas. Cell wall of archae is not made up of peptidoglycan like that of eubacteria. Their cell wall is made up of complex polysaccharides and complex polypeptide. Their cell wall is not a unit membrane, while in eubacteria the cell membrane is unit membrane.

Answer 2

So do you think that A. would be the best choice?

Answer 3

Actually I'm thinking that both B and D sound right but I dont know which one would be considered more right

Answer 4

No looking at it again A makes even more sense than the other two sorry I'm a little tired brain isn't working now lol

Answer 5
