Questions Related to biodiversity and need of classification
Bacillus subtilis are
-
Hay bacteria
-
Nitrifying bacteria
-
Ammonifying bacteria
-
Intestinal bacteria
Bacillus subtilis are also called as hay bacillus. They are gram-positive bacteria. They are commonly found in hay or upper layer of soil. Hence, they are called as hay bacteria. They are also found in the GI tract of ruminants and humans. They are obligate aerobes.
Syphilis causing bacterium Treponema pallidum belongs to the group
-
Rickettsiae
-
Bacillus
-
Actinomycetes
-
Spirillum
Treponema pallidum is a motile spirochaete bacterium that causes sexually transmitted disease syphilis. It is a helically coiled microorganism. It belongs to the group Spirillum. It is a gram-negative bacteria.
Prokaryotic algae are
-
Phycomyceae
-
Myxophyceae
-
Cyanobacteria
-
Both B and C
Myxophyceae is the other name for blue green algae or Cyanobacteria. It is a prokaryotic unicellular organism. It lacks membrane bound organelles like mitochondria, golgi complex. It also lacks true nucleus. Incipient nucleus or nucleoid is present in it. Incipient nucleus is a genetic material without nuclear envelope.
Cyanophyceae (Blue Green Algae) belongs to
-
Plantae
-
Protista
-
Monera
-
Metaphyta
Monera kingdom includes prokaryotic unicellular organisms. They lack membrane-bound organelles like mitochondria, Golgi complex. They also lack a true nucleus. Instead, they have nucleoid, genetic material without a nuclear envelope. Examples include bacteria, Cyanophyceae (Blue-Green algae).
Osmotrophs are
-
Bacteria
-
Fungi
-
Both A and B
-
Algae
Osmotrophs are heterotrophs which absorb organic substance in solution form.
Peptidoglycan is characteristic constituent of cell wall in
-
Archaebacteria and Eukaryotes
-
Eubacteria and unicellular Eukaryotes
-
Bacteria and Cyanobacteria
-
Monera and Protista
Bacteria and cyanobacteria both are prokaryotic organisms. They share many similarities. They both lack true cell organelles. They both posses nucleoid instead of a true nucleus. Peptidoglycan is the characteristic constituent of a cell wall in both bacteria and cyanobacteria. They both posses saprophytic mode of life. They both are similar in cell division as well.
Kingdom monera includes
-
Bacteria
-
Nitrogen fixing organisms
-
Cyanophyceae
-
All of the above
Monera is non-nucleated unicellular organisms. They are prokaryotes. They have a cell wall. They have no membrane-bound organelles such as mitochondria, Golgi complex. They lack a true nucleus. Instead, they have nucleoid, genetic material without a nuclear membrane. Examples include Bacteria, cyanophyceae (Blue-Green algae), Nitrogen-fixing organisms etc.
Kingdom monera includes
-
Prokaryotes only
-
Eukaryotes only
-
Both A and B
-
Mesocaryotes only
Kingdom Monera includes prokaryotic organisms only. They are unicellular organisms. They are made up of single cell bound by plasma membrane and lack membrane-bound organelles like mitochondria, Golgi bodies. They lack a true nucleus as well. Instead, they possess genetic material without nuclear envelope called as the nucleoid. They also contain ribosomes in the cytoplasm. The example includes bacteria, Blue-green algae.
Spirulina belongs to the kingdom
-
Monera
-
Protista
-
Plantae
-
Fungi
Kingdom Monera includes prokaryotic unicellular microorganisms. They lack membrane-bound organelles like mitochondria, golgi complex. They also lack true nucleus. Instead, they have nucleoid, a genetic material without nuclear envelope. They have cell wall. Examples include bacteria, Cyanobacteria like Spirulina.

-
Mycoplasma
-
Slime moulds
-
Archaebacteria
-
Eubacteria
