Archaebacteria differ from other bacteria in having a different cell wall structure. They lack peptidoglyan in cell wall and possess a monolayer of branched fatty acids attached to glycerol by ether bonds in their cell membranes.

Assertion : Eukaryotic cells have more DNA than prokaryotic cells Reason : Eukaryotes are more complex than prokaryotes genetically
1 Both Assertion and Reason are true and Reason is the correct explanation of Assertion.
2 Both Assertion and Reason are true but Reason is not the correct explanation of Assertion
3 Assertion is true but Reason is false.
4 Both Assertion and Reason are false.
Explanation:
Genetically eukaryotes are more complex than prokaryotes and eukaryotic cells have more DNA than prokaryotes. In prokaryotes , DNA is not associated with any histone proteins, amount of DNA is low in prokaryotic cell and remains same throughout life. In eukaryotes, DNA is associated with histone proteins , amount of DNA is higher in eukaryotes.

Which among the following are the smallest living cells, known without a definite cell wall, pathogenic to plants as well as animals and can survive without oxygen ?
1 Pseudomonas
2 Mycoplasma
3 Nostoc
4 Bacillus
Explanation:
Mycoplasma are smallest, prokaryotic organisms which lack cell wall. They are pleomorphic in nature. These are pathogenic on both plants and animals.

Which one of the following is the most abundant group of microorganisms?
1 Viroids
2 Viruses
3 Protists
4 Bacteria
Explanation:
Bacteria are the sole members of the Kingdom Monera. They are the most abundant micro-organisms. Bacteria occur almost everywhere.

The Cyanobacteria are also referred to as
1 Slime moulds
2 Protists
3 Golden algae
4 Blue - green algae
Explanation:
Cyanobacteria consists of two groups of photosynthetic eubacteria. Cyanobacteria appear blue green coloured because of its pigments chlorophyll (green) and phytocyanin (blue). Therefore they are called Blue-green algae.
