The rumen of cattle is the site of fermentation of cellulose fibres through the action of
1 archaebacteria
2 cyanobacteria
3 mycoplasmas
4 spirochaetes
Explanation:
Archaebacteria is a group of kingdom monera which is found in extreme habitats such as hot springs, marshy areas. - Archaea is a domain of single celled organisms these microorganisms lack cell nuclei. - Archaebacteria have the capability to produce methane i.e. are methanogens.

Heterocysts are found in:
1 Aspergillus
2 Nostoc
3 Cystopus
4 Ulothrix
Explanation:
A heterocyst is a differentiated cyanobacterial cell that carries out nitrogen fixation. - It is the site for nitrogen fixation under aerobic conditions. - Heterocysts are found in many species of filamentous blue-green algae. They are cells of slightly larger size and with a more thickned wall than the vegetative cells. - Example-Nostoc, Anabaena etc.

The site of respiration in bacteria is:
1 microsome
2 mesosomes
3 episome
4 ribosome
Explanation:
Mesosomes is a convoluted membranous structure formed in prokaryotic cell by the invagination of the plasma-membrane. - It helps in the synthesis of the cell membrane, replication of DNA, and protein synthesis. - It also involved in septum formation during cell division. - It perform the function of mitochondria in bacteria.

Murein is not found in the cell wall of ........
1 Cyanobactria
2 Diatoms
3 Nostoc
4 Eubacteria
Explanation:
Murein (peptidoglycan) found in cell wall of cyanobacteria \& eubacteria. Nostoc is a genus of cyanobacteria. Diatoms are photosynthetic protist, wall of diatoms rich in silica and other minerals. Hence murein is not found in the cell wall of diatoms.

The cells of the bacterium Streptococcus remain arranged in the form of:
1 irregular cluster
2 chain
3 plate
4 cube
Explanation:
Streptococci are Gram-positive, non-motile non-spore forming, catalase-negative bacteria that occur in pairs or chains. Most Streptococci are facultative anaerobes and some are obligate anaerobes. The cells of the bacterium Streptococcus remain arranged in the chain form of different length.
