Question

Natural system of classification was proposed by

• A. Bentham and Hooker
• B. Hutchinson
• C. Whittaker
• D. Engler and Prantl

Hint:

Remember:
• Bentham and Hooker $\rightarrow$ Natural Classification
• Engler and Prantl $\rightarrow$ Phylogenetic Classification
• Hutchinson $\rightarrow$ Phylogenetic Classification
• Whittaker $\rightarrow$ Five Kingdom Classification

Answer 1

The Correct Option is A

Concept: Classification systems evolved from artificial to natural to phylogenetic. Natural systems use many morphological traits to reflect overall similarity, making them more reliable than single-trait artificial systems.

Step 1: Recall Bentham and Hooker's work.
Their "Genera Plantarum" arranged plants by natural affinities using numerous characters, establishing a widely accepted natural system. Correct.

Step 2: Check Hutchinson.
Hutchinson proposed a phylogenetic system emphasising evolutionary descent, not a natural system. Incorrect.

Step 3: Check Whittaker.
Whittaker gave the Five Kingdom classification for all organisms, not specifically a plant natural system. Incorrect.

Step 4: Check Engler and Prantl.
Their system was phylogenetic, based on evolutionary concepts. Incorrect.

Final Answer: Bentham and Hooker (option A).
