Question

Two kingdom classification was given by ______
A. Linnaeus
B. Mendel
C. Whittaker
D. None of these

Answer 1

Hint: ​​Carolus Linnaeus proposed the two-kingdom categorization. He divided living organisms into two kingdoms: Plantae and Animalia.
The nutrition and movement of living beings are used to categorise and classify them. All organisms that cannot move and prepare their own food (autotrophs) belong to the Plant Kingdom, while all moving species that can move and rely on others for their sustenance belong to the Animal Kingdom (heterotrophs).

Complete answer:
Option A: Carolus Linnaeus proposed the 'Two-Kingdom Classification,' which was one of the first classification systems. Living organisms are divided into two main kingdoms: the plant kingdom and the animal kingdom, according to the two-kingdom categorization.
So, option A is correct.
Option B: In the \[1800\]s, Gregor Mendel was an Austrian scientist, teacher, and Augustinian priest. While residing in a monastery, he experimented on garden pea hybrids and is regarded as the father of modern genetics.
So, option B is not correct.
Option C: Robert Harding Whittaker was a plant ecologist in the United States. He was the first to suggest the Animalia, Plantae, Fungi, Protista, and Monera taxonomy classifications for the world's biota.
So, option C is not correct.
Option D: Carolus Linnaeus proposed the two-kingdom categorization. He divided living organisms into two kingdoms: Plantae and Animalia.
So, option D is not correct.

So, option A is the correct answer.

Additional information:
Drawbacks of two kingdom classification:
There are photosynthetic and non-photosynthetic species among the plants.
Fungi are organisms that do not have chlorophyll. They are heterotrophic in nature. However, they are surrounded by greenery.
Certain organisms have both plant and animal features. Sponges and Euglena, for example.
The role of prokaryotes has been completely overlooked.

Note:
Plantae comprises both photosynthetic and non-photosynthetic fungi, as well as bacteria (Prokaryotes). Multicellular animals, often known as metazoans, and unicellular protozoans make up the kingdom Animalia.
