Two kingdom classification was established by:a)Huxleyb)John Rayc)Lamarckd)LinnaeusCorrect answer is option 'D'. Can you explain this answer?

Question

Answer

The two-kingdom classification was proposed by Carolus Linnaeus. He categorised and classified the living organisms on the basis of nutrition and mobility. The living organisms were classified into Kingdom Plantae and Kingdom Animalia.

Answer

Two classification system was proposed by Carolos Linnaeus in 1758. Carolous Linnaeus is regarded as father of modern taxonomy, He is the author of two famous books Systema Nature and Species Plantarum.

Answer

The correct answer is option 'D' - Linnaeus.

Linnaeus, also known as Carl Linnaeus, was a Swedish botanist, zoologist, and physician who is considered the father of modern taxonomy. He is famous for his work in developing a system of classification for living organisms.

Linnaeus developed a hierarchical system of classification that grouped organisms into categories based on their similarities and differences. He classified organisms into two main kingdoms, namely, the Plantae kingdom and the Animalia kingdom. This system of classification is known as the two-kingdom classification.

Below are the key points explaining Linnaeus' two-kingdom classification system:

1. Kingdom Plantae:
- This kingdom includes all the plants, including mosses, ferns, gymnosperms, and angiosperms.
- Plants are multicellular organisms that have cell walls made up of cellulose.
- They are autotrophs, meaning they can produce their own food through photosynthesis.

2. Kingdom Animalia:
- This kingdom includes all the animals, including insects, mammals, birds, fish, and reptiles.
- Animals are multicellular organisms that lack cell walls.
- They are heterotrophs, meaning they obtain their food by consuming other organisms.

Why Linnaeus established the two-kingdom classification system:
Linnaeus established this classification system to organize and categorize the vast diversity of living organisms present on Earth. His system provided a basic framework for understanding the relationships and characteristics of different organisms. It was a significant step in the field of biology and helped scientists to study and classify organisms more effectively.

Limitations of the two-kingdom classification system:
While Linnaeus' two-kingdom classification system was groundbreaking at the time, it has some limitations. Some organisms, such as fungi, do not fit neatly into either the Plantae or Animalia kingdom. Additionally, the system does not account for the many other types of organisms found today, such as bacteria, protists, and archaea. As our understanding of the diversity of life has expanded, scientists have developed more complex classification systems, such as the five-kingdom classification system and the three-domain system.

In conclusion, Linnaeus established the two-kingdom classification system, which categorized organisms into the Plantae and Animalia kingdoms. This system provided a foundation for the study of taxonomy and understanding the relationships between different organisms. However, it has been expanded upon in modern classification systems to accommodate the increasing knowledge of the diversity of life.
