Each of the following characteristics represent a Kingdom proposed by Whittaker. Arrange the following in increasing order of complexity of body organization. A. Multicellular heterotrophs with cell wall made of chitin. B. Heterotrophs with tissue/organ/organ system level of body organization. C. Prokaryotes with cell wall made of polysaccharides and amino acids. D. Eukaryotic autotrophs with tissue/organ level of body organization. E. Eukaryotes with cellular body organization. Choose the correct answer from the options given below :
Answer: (D) C, E, A, D, B. Answer: (D) C, E, A, D, B Solution: In increasing complexity of body organisation: C = Monera (prokaryotes, polysaccharide+amino acid wall, cellular), then E = Protista (eukaryotes, cellular), then A = Fungi (multicellular heterotrophs, chitin wall, loose tissue), then D = Plantae (eukaryotic autotrophs, tissue/organ), then B = Animalia (tissue/organ/organ-system).
- A.A, C, E, D, B
- B.C, E, A, B, D
- C.A, C, E, B, D
- D.C, E, A, D, B✓
Correct Answer
(D) C, E, A, D, B
Solution & Explanation
Answer: (D) C, E, A, D, B Solution: In increasing complexity of body organisation: C = Monera (prokaryotes, polysaccharide+amino acid wall, cellular), then E = Protista (eukaryotes, cellular), then A = Fungi (multicellular heterotrophs, chitin wall, loose tissue), then D = Plantae (eukaryotic autotrophs, tissue/organ), then B = Animalia (tissue/organ/organ-system). Order C, E, A, D, B = option (D). NCERT Reference: NCERT Class XI, Biological Classification, p.11, lines 116-129 — "Tissue/organ ... Tissue/organ/ organ system"
