Archaebacteria differ from eubacteria in
Show Hint
Archaebacteria have different cell membrane structures than other bacteria. The lipids in archaebacteria cell membranes are ether-linked compared to ester-linked in other bacteria. Archaebacteria are similar to bacteria in morphology, structure, shape, mode of reproduction, and nutrition.
- cell membrane structure
- mode of nutrition
- cell shape
- mode of reproduction.
The Correct Option is A
Solution and Explanation
Archaebacteria differ from eubacteria in cell membrane structure.
The archaebacteria are considered to be the 'ancient' bacteria that comprise extremophiles like methanogens, halophiles, and thermophiles. They represent some of the most ancient life forms that continue to exist today. Generally, archaebacteria have the same shape, size, nutrition, and appearance as bacteria. They multiply by the means of binary fission.
However, archaebacteria cell walls lack peptidoglycan. They also have different membrane lipid bonds in comparison to bacteria and eukarya. Archea membrane lipids have ether bonds whereas bacteria have ester-linked lipids.
Therefore, the correct answer is option A.

Biological Classification
The process of grouping living organisms into categories is called biological classification. The most modern 5-kingdom classification was put ahead by an eminent scientist R.H.Whittaker. The five-kingdom classification is based on the criteria like cell structure, mode of nutrition, body form, and reproduction. One of the most important characteristics of this system is that it follows the evolutionary sequence of living organisms. The organisms are classified into distinct taxa or levels like Kingdom, Phylum, Division, Class, Order, Family, Genus, and Species. The 5 kingdoms are as follows:
