Which one of the following does not find a heterotrophs place in five kingdom system of classification?

  1. Bacteria

  2. Lichens

  3. Cyanobacteria

  4. Viruses
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Viruses are considered to be acellular as they do not have a defined cell wall, cell membrane, nucleus or nucleoid, cytoplasm and cellular organelles. For this reason, they cannot perform their metabolic activities on their own and are obligately dependent on the host cell machinery. Therefore, they do not find a place in the five-kingdom classification system. 

A. Bacteria are classified under Kingdom Monera as they have a prokaryotic cell.
B. Lichens are grouped under Kingdom Fungi.
C. Cyanobacteria are photosynthetic prokaryotes grouped under Kingdom Monera.
D. No kingdom is ascribed to the viruses.
Hence, the correct answer is 'Viruses'

Which of the following is the most commonly used classification scheme?

  1. Linnaeus, five kingdom scheme

  2. Whittaker, five kingdom scheme

  3. Darwin, five kingdom scheme

  4. Hooke, five kingdom scheme
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
R.H. Whittaker proposed the five kingdom classification in the year 1969. It is the modern or latest classification system of organisms which is most commonly used. It classifies the organisms in the groups Monera, Protista, Fungi, Plantae and Animalia. The classification is performed on the basis of the structure of cell, complexity of organisms, mode of nutrition and phylogenetic relationship.
Thus, the correct answer is option B.

Choose the incorrect match from the following in Whittaker's classification.

  1. Archeae - Monera

  2. Diatoms - Protista

  3. Lichens - Fungi

  4. Green algae - Plantae
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
A lichen is not a single organism, but the result of a partnership (mutualistic symbiosis) between a fungus and an alga or cyanobacteria. So they are not particularly classified under one single kingdom because it consists of two or more mutualistic symbiotic organisms.
So the correct option  is 'Lichens -fungi'.

Allergic asthma is a type of asthma that is triggered by an allergy (for example, pollen or mold spores).

Dengue is transmitted by

  1. Aedes

  2. Male Anopheles

  3. Female Anopheles

  4. Tsetse fly
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Aedes aegypti, the principal mosquito vector of dengue viruses is an insect closely associated with humans and their dwellings. People not only provide the mosquitoes with blood meals but also water-holding containers in and around the home needed to complete their development. The mosquito lays her eggs on the sides of containers with water and eggs hatch into larvae after a rain or flooding. A larva changes into a pupa in about a week and into a mosquito in two days.
