Single Choice

Which of the following are true of archaebacteria? a. Presence of peptidoglycan cell wall b. Extreme halophytes c. Extreme thermophiles d. Methanogen Select the correct answer using the codes given.

A$$1, 2$$ and $$3$$
Correct Answer
B$$2, 3$$ and $$4$$
C$$1, 3$$ and $$4$$
D$$1, 2$$ and $$4$$

Solution

The cell wall of archaebacteria consists of pseudomurein (prevents the organism from the effect of lysozyme and it separates the outer-most S-layer from the plasma membrane), is a differ form of peptidoglycan.
This bacteria survives in extreme acidic, metallic as well as above temperature of boiling point, i.e., extreme thermophilic.
This is capable of producing methane. i.e., methanogen (which can be used in making of methadone medicine for sewage treatment).
Halophytes are a kind of salt tolerant plants.
So, the correct option is C.
