Biological Classification

Whittaker's five kingdoms come first: Monera, Protista, Fungi, then Plantae and Animalia, plus viruses, viroids, and lichens. Expect recall questions that match organisms to kingdoms or pick the odd criterion out.

Weightage: what the paper actually did

Biological Classification carried 1 question in the NEET 2026 paper. One paper is a data point, not a destiny: NTA moves weight between chapters every cycle, which is why the weightage tables deserve care. The stable facts are the paper's shape: 180 questions, 720 marks, +4 right, −1 wrong.

Question 1 · NEET 2026

The main criteria used for Five Kingdom Classification proposed By R.H. Whittaker (1969) included. Choose the correct answer from the options given below: I. Cell structure II. Body organization III. Presence of flagellum IV. Reproduction V. Phylogenetic relationships
  1. A.A, B, C, D and E
  2. B.B, C and D only
  3. C.A, B, D and E only
  4. D.A, B and E only
Answer and explanation

Answer: C

Whittaker's five kingdom classification was based on cell structure (A), body organisation (B), mode of nutrition, reproduction (D) and phylogenetic relationships (E). Presence of a flagellum (C) was not one of the main criteria, so the correct set is A, B, D and E.
