One of the following is not the characteristic feature of Cyanobacteria
1 They are multi cellular
2 They form colonies
3 They form blooms in polluted water bodies
4 They can fix atmospheric nitrogen
Explanation:
Cyanobacteria also known as Cyanophyta are a group of Gram negative bacteria that obtain energy via photosynthesis. They are unicellular organism. - Cyanobacteria are a special category of bacteria that can perform photosynthesis. - They have chlorophyll and carry out oxygen producing photosynthesis as much as plant and eukaryotic algae.

Select the most successful group of organism on the surface of our globe
1 Gram positive heterotrophs
2 Gram negative photosynthetic cyanobacteria
3 Chemoautotrophic bacteria
4 Photoautotrophic bacteria
Explanation:
Cyanobacteria are a group of bacteria that are able to do photosynthesis. - A family of photosynthetic bacteria known as Cyanobacteria are widely dispersed in both aquatic and terrestrial. Hence, the most successful group of organism on the surface of our globe is Gram negative photosynthetic Cyanobacteria.

The characteristic cells wall material peptidoglycan has another covering of lipopolysaccharides. This specialized condition is found in
1 Eubacteria Gram positive
2 Eubacteria Gram negative
3 All eukaryotes
4 Both (a) and (b)
Explanation:
Eubacteria is a genus of Gram-positive bacteria in the family Eubacteriaceae. These bacteria are characterised by rigid cell wall. - They may be either be motile or non-motile. - Gram- negative bacteria are surrounded by a thin peptidoglycan cell wall which itself is surrounded by an outer membrane containing lipopolysaccharide.

Gram negative heterotrophic bacteria that can biodegrade a variety of natural as well as manmade organic compounds, such as petroleum products, include
1 cyanobacteria
2 clostridia
3 archaebateria
4 none of these
Explanation:
Bacteria with the ability to degrade hydrocarbon are named as hydrocarbon degrading bacteria. - Biodegradation of hydrocarbons can occur under aerobic and anaerobic conditions. - Waste materials can be broken down into simple, non-toxic substances by microorganism.
