Five kingdom system of classification suggested by R.H. Whittaker is not based on: 
R.H Whittaker in 1969 proposed five kingdom classification. In this system the arrangement of five kingdoms is based on following three criteria:
Which one of the following fungi contains hallucinogens? 
Several mushrooms such as Amanita muscaria, Psilocybe mexicana and Panaeolus spp. secrete hallucinogenic substances like psilocybin and psilocin. These substances may destroy brain cells and perception power of human beings.
Archaebacteria differ from eubacteria in: 
Which of the following shows coiled RNA strand and capsomeres? 
TMV (Tobacco Mosaic Virus) is a rodshaped virus. The rod has a core which contains helically coiled single stranded RNA . There is a protective covering of protein called capsid around the infective part. Capsid consists of small subunits called capsomeres and has antigenic property.
Viruses have: 
The motile bacteria are able to move by: 
Motile bacteria have thin filamentous extensions from their cell wall called flagella.
Which one of the following matches is correct ? [2015 ]
Let us find the correct answer from the following,
Option A: Alternaria belongs to deuteromycetes, which are also known as imperfect fungi, since they reproduce through asexual reproduction or vegetative reproduction. Deuteromycetes reproduces by asexual spores known as conidia. Some members of deuteromycete are parasitic and saprophytes, while a majority of them are decomposers of litter and they help in mineral cycling. Alternaria lack sexual reproduction. Therefore, this is the correct option.
Option B: Mucor is a type of fungus seen in soil and plant leaves. They belongs to the category of phycomycetes and they undergoes asexual reproduction by zoospores or aplanospores. Other examples for phycomycetes are Rhizopus and Albugo. Therefore, this is the incorrect option.
Option C: Agaricus, which is also known as mushroom, belongs to basidiomycetes. They grow on soil, logs and tree stumps. Asexual spores are absent, but vegetative reproduction is common in them.These are saprophytic fungi and are not parasitic. Ustillago and Puccinia are other examples for basidiomycetes. Therefore, this is the incorrect option.
Option D: Phytophthora belongs to algal fungi, also known as phycomycetes. These are mostly found in aquatic habitats. They have coenocytic and septate mycelium. Therefore, this is the incorrect option.
True nucleus is absent in : [2015 RS]
Anabaena is a cyanobacteria which lack a true nucleus because of absence of nuclear membrane.
Which of the following structures is not found in a prokaryotic cell? 
In a prokaryotic cell, nuclear envelope is not found. It means genetic material (DNA) is not enclosed by any envelope and lies in direct contact with the cytoplasm.
The imperfect fungi which are decomposer of litter and help in mineral cycling belong to: 
So, the correct option is D.
The structures that help some bacteria to attach to rocks and / or host tissues are: 
Fimbriae are small bristle-like fibres sprouting out of the cell. In some bacteria, they are known to help is attachment to rocks in streams and also to the host tissues.
Pick up the wrong statement 
The kingdom Monera possesses unicellular organisms (e.g - bacteria) having no nuclear membrane.
Which one is wrong statement? 
So, the correct answer is option A.
In which group of organisms the cell walls form two thin overlapping shells which fit together? 
In chrysophytes, the cell walls form two thin overplapping shells holding together. The body of Diatoms appears like soap box due to overlapping shells.
Choose the wrong statements: 
A. Neurospora has a short life cycle and hence, it is used in genetical and biochemical studies. Hence, statement A is correct.
B. Morels or Morchella, commonly known as a sponge mushroom produces fruiting body basidiocarp which is edible. Truffles are the ascomycetes which also produce edible fruiting bodies. Hence, statement B is incorrect.
C. Yeast is a unicellular i.e. single-celled and non-mycelial saprophytic fungus. In anaerobic conditions, yeast converts sugar into alcohol with the release of carbon dioxide and some energy. Due to this, yeast is used in a fermentation process. Hence, statement C is correct.
D. Penicillium is a saprophytic fungus belonging to Ascomycetes. The mycelium is profusely branched and septate. Cells are thin walled with many nuclei in them. Thus, it is multicellular. Penicillin is an antibiotic produced from Penicillium. Hence, statement D is correct.
So, the correct answer is 'Morels and truffles are poisonous mushrooms'.
Which of the following are the most suitable indicators of SO2 pollution in the environment? 
Lichens cannot grow in the place where sulpher dioxide, pollutant is available in the environment.
Which of the following statements is wrong for viroids? 
One of the major components of cell wall of most fungi is 
So, the correct answer is option A, chitin.
Which one of the following statements is wrong? 
Now, let us find the solution from the options:
Thus, the correct answer is option (C) Eubactaria are also called false bacteria.
Chrysophytes, Euglenoids, Dinoflagellates and Slime moulds are included in the kingdom 
All unicellular eukaryotic organism like diatoms, desmids (chrysophytes), euglenoids, dinoflagellates and slime mould are included in Protista.
Characteristics of Kingdom Protista:
