Life is not possible without a cell. Viruses do not have cells. As it is so, it does not have life when it outside a living cell. As it enters a living cell, it will show the features of life forms. It makes use of the components of the host cell and continues to live. Though it does not have a cell, it can continue its life only after entering a host cell and by making use of its components.

Not much differences are there. In the place of ‘Order’ in animal classification, plant classification has series. And in the place of ‘Phylum’ in animal classification, plant classification has ‘Division’.

a. True 

b. False, Theophrastus 

c. False, John Ray 

d. False, Carl Linnaeus

Viruses exhibit living nature only when they enter the host cells. On other occasions, they do not exhibit living nature. But organisms in Monera are not like that.

Taxonomic keys are scientific indicators used to identify and classify plants and animals. Dichotomous keys is one of the popular taxonomic keys.

Lion having the scientific name Pantheraleo.

Lion and Tiger belongs to same Genus ‘Panthera’

The classification of Linnaeus had only two kingdoms, plants, and animals. He did not consider bacteria, protozoa, fungus, etc. Certain characters of animals considered by Linnaeus for classification are found in both the kingdoms, eg. photosynthesis found in plants is seen in some animals like Euglena. Certain characters of animals can be seen in plants also, eg certain types of algae. But Whittaker adopted the method of having five kingdoms including protozoa and bacteria.

• Monera, 
• Protista 
• fungi 
• Plantae 
• animalia

Some lower organisms share the characters of both animals and plants. So it is difficult to recognize them as plants or animals. Linnaeus considered only plants and animals for his classification. Microscopic organisms like bacteria, fungus, protozoa, etc were not included either in plant kingdom or in animal kingdom. Certain animals which were included in the classification of Linnaeus show characters of both the animal and plant kingdoms. Eg: Euglena protozoan shows locomotory movements like animals, but it contains chlorophyll like plants.

• Eliminated from Phylum Chordates — Butterfly, Cockroach Reason — Animals with vertebral columns alone are included in the phylum chordates.
• Eliminated from Class Mammalia — Bird (Pigeon) Reason — Animals that give birth to young ones alone included in this group.
• Eliminated from the order Carnivora — Rabbit Reason — Carnivores alone included in this order.
• Eliminated from the family Felidae — Bear Reason — It does not have retractile claws.
• Eliminated from the Genus Felis — Lion, tiger Reason — Animals having small body and without roaring sound are included.
• Eliminated from the Species domestic — Wild Cat Reason — It has the basic features of cat

Bacteria, Fungus, etc were not included in two kingdom classification.

Dichotomous key is the most popular among these. Each indicator contains 2 options for selection. By selecting the characteristic feature of the organism to be identified it can be recognized and classified.

In ancient times knowledge regarding the characteristics of micro organisms was limited. It was found out that the cell structure and physiology of archaebacteria belongs to kingdom monera are quite different from other bacteria. Hence kingdom monera was divided into two kingdoms – Archae and Bacteria. Besides another level namely ‘domain’ was added above kingdom. Thus 6 kingdom classification came into existence

a. R H Whittaker 

b. Monera 

c. Father of Taxonomy 

d. Crow 

e. Theophrastus

a. Animals 

b. Fungi 

c. Amoeba 

d. Plants

In five kingdom classification bacteria, amoeba, fungus, plants, and animals were included in separate kingdoms according to their characteristics.

Man can be included in Class Mam-malia and Phylum Chordata.

Cockroach, Butterfly, Bird, Rabbit, Cat, Tiger, Lion, bear

Viruses have no specific cell structure. Genetic material and a protein sheath alone are present. It is difficult to destroy them. They live only in living cells. They are dead or inactive outside the cell. It multiplies inside the host cell and destroys it.

1. Kingdom 

2. Phylum Chordata 

3. Mammalia 

4. Mammalia 

5. Species

a. Carl Vaus 

b. Historia Generalis Plantarum

As viruses have no cellular structure, it is not possible to include in any of the classifications mentioned.

Answer is Virus

a. Rabbit – Others including order Carnivora

b. Carl Linnaeus – He is the Father of Modern Taxonomy. Others are different levels of classification.

Coconut – Cocos nucifera 

Paddy – Oryza sativa 

Wheat – Triticum aestivum 

Crow – Corvus splendens 

Mango – Mangifera indica 

Grapes – Vitis vinifera
