NEET 2026 (Phase 1) · BiologyKingdom criteriaPrevious Year Question
The main criteria used for Five Kingdom Classification proposed By R.H. Whittaker (1969) included : A. Cell structure B. Body organization C. Presence of flagellum D. Reproduction E. Phylogenetic relationships Choose the correct answer from the options given below :
- A.A, B, C, D and E
- B.B, C and D only
- C.A, B, D and E only✓
- D.A, B and E only
Correct Answer
(C) A, B, D and E only
Solution & Explanation
Answer: (C) A, B, D and E only Solution: Whittaker's main criteria were cell structure, body organisation, mode of nutrition, reproduction and phylogenetic relationships. Among the listed options, A (cell structure), B (body organisation), D (reproduction) and E (phylogenetic relationships) are correct; C (presence of flagellum) was NOT a criterion, so it is excluded. NCERT Reference: NCERT Class XI, Biological Classification, p.11, lines 20-22 — "the main criteria for classification used by him include cell structure, body organisation, mode of nutrition, reproduction and phylogenetic relationships"
