The five kingdom classification was proposed by
Five kingdom classification was proposed by R.H. Whittaker in 1969.
The kingdoms identified by him were:
All prokaryotic, unicellular organisms are included under kingdom
Identify from the following, the only taxonomic category that has a real existence.
Species is the lowest or basic taxonomic category which consists of one or more natural populations of individuals that resemble one another more closely than individuals of other species, interbreed freely, have a distinct genetic setup and are reproductively isolated from others e.g., Panthera Leo (Lion), Mangifera indica (Mango), Solanum tuberosum (Potato).
A peculiar group of dual organism which are formed by an association between an algae and a fungus.
Which among the five kingdom system of classification do not possess nuclear membrane?
The primitive prokaryotes responsible for the production of biogas from the dung of ruminant animals, include the
The cell wall of fungi consist of:
Chitin is a modified polysaccharide that contains nitrogen.
Chitin is synthesized from long-chain of N-acetylglucosamine polymer and is a glucose derivative.
This polysaccharide is a primary component of cell walls in the fungi, arthropod exoskeletons such as crustaceans and insects, mollusc's radula, cephalopod beaks, and fish.
Which one is important in nutrient recycle and act as decomposer and mineralisers of the biosphere
Fungi is important in nutrient cycle and acts as decomposer along with bacteria and minerlisers of the biosphere to regulate recycling of nutrients in the biosphere.
Which possess acellular structure?
Viruses are acellular, which means they don't have a cellular structure. Bacteriophages are viruses that infect the simplest living species, and are one of the most complex virus particles.
In five kingdom of classification, Whittaker assigned eukaryotes to
Prokaryotes differ from Eukaryotes in absence of:
Prokaryotes differ from Eukaryotes in absence of nuclear membrane and membrane-bounded organelles like mitochondria, Golgi bodies etc.
Which among the following is photosynthetic as well as saprophytic?
Euglena is a special type of organism as it shows mixotrophic mode of nutrition i.e. in presence of sunlight it is phototrophic and in absence of sunlight it derives nutrition by saprophytic modes. In the presence of sunlight it is autotrophic.
In fungus, reserve food material is
Which is NOT the characteristic of viroids?
Which kingdom brought Chlorella and Chlamydomonas with Paramoecium and Amoeba?
Kingdom Protista has brought together Chlamydomonas, Chlorella which were earlier placed in Algae (within plants and both having cell walls) with Paramoecium and Amoeba which were earlier placed in the animal kingdom which lack cell wall.
Which of the following is incorrect about Cyanobacteria?
A heterocyst is a differentiated cyanobacterial cell that carries out nitrogen fixation. The heterocysts function as the sites for nitrogen fixation under aerobic conditions. They are formed in response to lack of fixed nitrogen.
Hence, the correct option is 'B'
A non-photosynthetic aerobic nitrogen fixing soil bacterium is:
In which class of fungi the mushroom belongs to?
The Agaricomycetes belong to the Basidiomycota division of fungi. With the addition of Auriculariales and Sebacinales, the taxon is nearly identical to that established by Hibbett & Thorn for the Homobasidiomycetes.
(a) Contain protein
(b) Contain DNA
(c) Are susceptible to antibiotics
(d) Are intracellular
So, the correct option is B: '(a) & (d)'.
Classification given by Bentham and Hooker is
Plant cells differ from animal cells in
Plant cells have a cell wall made up of cellulose and chloroplast that contain chlorophyll for photosynthesis. Animal cell lacks both cell wall and chloroplast.
The asexual reproduction in fungi takes place by
Asexual reproduction in fungi takes place by conidia, zoospore, sporangiospores, chlamydospore and oidia.
In some fungi, the spores are not formed inside a sporangium. They are born free on the tips of special branches called conidiophores. These spores thus formed are called conidiophores for example in Penicillium.

Which is the possible region of respiration in bacteria
Which of the following is not a viral disease?
So, the correct answer is 'Tuberculosis'.
Which of the following statement is correct?
Therefore, Lichens are the indicators of pollutants or pollution and do not grow in polluted areas.
