Biological Classification

Each of the following characteristics represents a kingdom proposed by Whittaker. Arrange the following in increasing order of complexity of body organisation.

A. Multicellular heterotrophs with a cell wall made of chitin.

B. Heterotrophs with tissue/organ/organ-system level of body organisation.

C. Prokaryotes with a cell wall made of polysaccharides and amino acids.

D. Eukaryotic autotrophs with tissue/organ level of body organisation.

E. Eukaryotes with cellular body organisation.

Choose the correct answer from the options given below:

  1. A.A, C, E, B, D
  2. B.C, E, A, D, B✓
  3. C.A, C, E, D, B
  4. D.C, E, A, B, D

Solution

Monera (prokaryotes with peptidoglycan walls, C) → Protista (unicellular eukaryotes, E) → Fungi (multicellular with chitin walls, A) → Plantae (tissue/organ level autotrophs, D) → Animalia (organ-system level heterotrophs, B). So C, E, A, D, B.
