Identify the correct statements regarding archaebacteria. |
(i) Archaebacteria differs from other bacteria in having different cell wall structure. |
(ii) Their cell wall is made up of cellulose and contains high amount of unsaturated fatty acid, which is responsible for their survival in extreme conditions. |
(iii) Thermoacidophiles have dual ability to tolerate high temperature as well as high acidity. |
A) (i) and (ii)
B) (ii) and (iii)
C) (i) and (iii)
D) (i), (ii) and (iii)
Correct Answer: C
Solution :
Bacterial cell wall is made up of protein, non- cellulosic ammo acid etc. Archaebacteria are characterized by the absence of peptidoglycan in their wall. Instead, the wall contains proteins and non-cellulosic polysaccharides. Thermoacidophiles have dual ability to tolerate high temperature as well as high acidity. They often live in hot sulphur springs, where the temperature may be as high as \[80{}^\circ C\] and pH as low as 2, e.g., Thermoplasma, Thermoproteus.You need to login to perform this action.
