Which of the following is a correct statement?
1 Mycoplasma have DNA, ribosome and cell wall.
2 Cyanobacteria are a group of autotrophic organisms classified under Kingdom Monera.
3 Bacteria are exclusively heterotrophic organisms.
4 Slime moulds are saprophytic organisms classified under Kingdom Monera.
Explanation:
Cyanobacteria or blue-green algae are the one of most successful autotrophic organisms. Cyanobacteria are the most self contained photosynthetic organisms. Cyanobacteria may be unicellular, colonial or filamentous. Ex-Oscillatoria.

Plasmid is
1 extragenetic material in mycoplasma
2 circular DNA in bacteria
3 extra DNA in bacteria
4 fragment of DNA inserted in bacteria for forming copies
Explanation:
A plasmid is a small circular DNA molecule found in bacteria and some other microscopic organism. The insertion of a DNA fragments into a bacterial plasmid with the enzymes DNA ligase. The plasmid is cut open with a restriction nuclease in this case one that produces cohesive ends and is mixed with DNA fragment to be cloned.

Which of the following statements is not true about bacterial cell?
1 Possess genetic material not bounded by nuclear membrane.
2 Small circular DNA molecules are present in the cytoplasm.
3 Pili and fimbriae are extracellular structures for motility.
4 The cell envelop is composed of glycocalyx, cell wall and plasma membrane.
Explanation:
Pili and Fimbriae- Pilli are hair like, cell wall of bacteria smaller that filagella are involved in the conjugation of bacterial cells, promoting the initial joining of mating pairs, short pili are known as fimbriae means for attachment on the substratum of the bacterial cell.

Choose the incorrect statement regarding Archaebacteria
1 They are halophiles and thermoacidophiles
2 The cell wall contains peptidoglycan
3 The cell membrane contains branched chain lipids
4 They are responsible for the production of Methane from the dung of animals
Explanation:
Archaebacteria:- It is unicellular, prokaryotic organism. The cell wall consist of complex proteins and non cellulosic polysaccharide but peptidoglycan is absent in cell wall. The cell membrane made up of branched chain of lipid due to the presence of lipid chains, they are resistant to high temperature, salinity, radiation and change in $\mathrm{pH}$.
