Question

Which one of the following characteristics of Archaea enablesthem to survive in extreme environments?

Answer 1

Hi @Elvia, welcome to OpenStudy!

Could you please list down the options?

Answer 2

Hi there thank you for coming to help

Answer 3

@Elvia Post here your options or edit your question for adding options..

Answer 4

Options a their ability to survive on other sources of energy if the required resources are not present.
B the presence of peptidoglycan in their cell wall which increases their ability to thrive in extreme conditions.
C their highly locomotive abilities which enable them to move suitable environments.

Answer 5

Hmm..option c makes no sense..How would locomotive abilities would help them in survival of extreme environments..
so its false.
and Peptidoglycan t's an important structural molecule in the cell walls..of bacteria and archea...it can not increase their ability to thrive in extreme environment..
So Only one option left..that would be your answer..


Plus..Archea are extremophiles.

They're extremely similar to bacteria except for habitats, shape, and ezymes.

Examples: thermophilic, hydrophllic, halophilic and they also contain different enzymes (like the ability to digest cellulose within cows and termites)

Answer 6

If you want to know more about Archea then read this ..

Answer 7

So I believe it would be a correct

Answer 8

Very helpful thank you

Answer 9

No problem ..

Answer 10

I'm going with A I believe that is the answer do you agree?

Answer 11

Let me ask @nincompoop he can answer better..

Answer 12

Ok

Answer 13

What are their sources of energy? Do you know?..:/

Answer 14

I'm sorry I don't have a clue

Answer 15

Archea or Archaebacteria include methanogens, thermoacidophiles and halobacteria
in the case of methanogens, they convert carbon dioxide and hydrogen into methane which they use as a biological generator of energy.

Answer 16

That does make senc

Answer 17

So I'm right it's A just checking with you first

Answer 18

Yup..but look..i wont say you to go with A..coz..
Peptidoglycan makes up the bacterial cell wall, and thus performs all the functions of a cell wall (structure, support, protection, cell division) ...
SUPPORT,+PROTECTION...=? what you think now??

Answer 19

I'm confused now

Answer 20

@Kayne What you say?

Answer 21

I need for sures because I can only miss one out of five

Answer 22

So A

Answer 23

only A makes sense..so A is correct...I'm sure..

Answer 24

@Ryaan I'm looking for it. From my source, it definitely can't be B because Archae do not contain the chemical peptidoglycan - the cell wall composition is different from that of bacteria. So, by elimination I'd say A. Looking for a relevant document.

Answer 26

Thank you so much for taking the time

Answer 27

Alright Kayne..But I have read in some books they contain Peptidoglycan..well..

Answer 28

I have 3 more questions are you two going to be on

Answer 29

This source as well says that they don't contain peptidoglycan or they can contain pseudo peptidoglycan: http://www.colorado.edu/eeb/EEBprojects/schmidtlab/studentres/EBIO3400/Lecture11.pdf

Answer 30

@Elvia you can post your questions and we'll help you to shed some light on them :)

Answer 31

Thank you so much

Answer 32

Thanks to kayne. actually

Answer 33

Thanks to you too @Ryaan :)

Answer 34

Lets go to elivia's another question :D @Kayne
