Example Question #322 : Gre Subject Test: Biology
What comprises the cell wall of archaea?
Possible Answers:
Pseudopeptidoglycan
Cellulose
Chitin
Peptidoglycan
Glycogen
Correct answer:
Pseudopeptidoglycan
Explanation:
The correct answer is pseudopeptidoglycan. This is molecularly different than peptidoglycan, which comprises the bacterial cell wall. However, both pseudopeptidoglycan and peptidoglycan cell walls are similar in function, shape and structure. Cellulose comprises the cell walls of plants, chitin comprises the cell walls of fungi and glycogen is the animal form of stored glucose, and is found in the liver and skeletal muscle.
