Questions Related to biodiversity and classification
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.
