Question

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

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

Answer 1

I have no idea about this one.. @Abhisar

Answer 2

Sorry fro the delay...I was busy some where else...I am actually doing two three things at once ...

Answer 3

Do you know what an Archaebacteria is?

Answer 4

Hold on..lol.

Answer 5

Isn't Archaebacteria like really early life forms..? They live in high temperatures, low pH, and high salinity..

Answer 6

Yes, Archae are primitive, they were first to born on our planet and they are present nowadays with their primitive characters. They have the uniques feature of being able to livein harshest areas like the one you mentioned..

Answer 7

Now, what makes them different from other bacteria?
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 8

Well..their cell structures are different.

Answer 9

Archae don't form spores..

Answer 10

So what do you think should we select from the given options?

Answer 11

B..?

Answer 12

It can either be B or D

Answer 13

Okay, I'm going to go with D..it sounds like a better choice..thanks again!
