Question

Who first classified the plant kingdom?

• A. Carlous Linnaeus
• B. R.H. Whittaker
• C. Bentham & Hooker

Hint:

Linnaeus is known for his development of binomial nomenclature and for being the first to classify the plant kingdom.

Answer 1

The Correct Option is A

Step 1: Linnaeus’s classification system.
Carlous Linnaeus, a Swedish botanist, is credited with being the first to develop a modern classification system for plants and animals. His system of binomial nomenclature and hierarchical classification laid the foundation for how organisms are grouped.
Step 2: Other contributions.
Later, Bentham & Hooker proposed a broader classification scheme, and R.H. Whittaker proposed a 5-kingdom classification system that included Monera, Protista, Fungi, Plantae, and Animalia. However, Linnaeus was the first to develop a classification system for plants.
Step 3: Conclusion.
Thus, Carlous Linnaeus was the first to classify the plant kingdom, corresponding to option (a).

Answer 2

Step 1: A modern system for classifying and naming plants and animals (binomial nomenclature) was first developed by a Swedish botanist.

Step 2: That botanist is Carl (Carlous) Linnaeus.

Step 3: Later scientists like Bentham & Hooker and R.H. Whittaker built further classification systems, but Linnaeus came first.

Step 4: So the first to classify the plant kingdom this way was Linnaeus — option (A).

Answer 3

Elimination by timeline.
R.H. Whittaker put forward his five-kingdom scheme only in 1969, and Bentham & Hooker published their classification of plants in the 1860s-80s. Carl (Carlous) Linnaeus, however, had already grouped the plant kingdom into classes and orders in his "Species Plantarum" back in 1753, decades before either of the other two systems existed. Ruling out the later two names by date leaves Linnaeus as the one who classified the plant kingdom first, option (a).
