Question

2. How did whittaker classify organisms ? state the
different stages.​

Answer 1

Answer:

Some biologists classified organisms into plants and animals. ... Whitaker proposed that organisms should be broadly divided into kingdoms, based on certain characters like the structure of the cell, mode of nutrition, the source of nutrition, interrelationship, body organization, and reproduction.

Explanation:

Linnaeus later classified all living organisms into two kingdoms – Plantae and Animalia. Whittaker proposed an elaborate five kingdom classification – Monera, Protista, Fungi, Plantae and Animalia. ... In the five kingdom classification, bacteria are included in Kingdom Monera.

Answer 2

Answer:

A Five Kingdom Classification was proposed by R.H. Whittaker in 1969.

Explanation:

5 Kingdom of his classification are:

1. Monera
2. Protista
3. Fungi
4. Plantae
5. Animalia

• He primarily uses cell structure, thallus organisation, mode of nourishment, reproduction, and phylogenetic relationships as classification criteria.
• The five-kingdom system of classifying living things took many factors into account and is still the most effective one.
• In the previous classification scheme, two extremely diverse organisms were placed together based solely on that one trait. For instance, the presence of the cell wall led to the fungi and plants being grouped together. The similar method was used to combine multicellular and unicellular creatures.
