C. Short Answer Type
1. Rearrange the following categories of classification in their proper sequence starting with the highest.
species, family, genus, class, order, phylum
Solution C.1.
Phylum → Class → Order → Family → Genus → Species
2. Give the scientific names of man, domestic cat, and peepal tree.
Solution C.2.
Solution C.3.
In science, people from different countries with different languages have to read about each others research. So, it was necessary to eliminate any possible confusion created by local names. Scientific names are based on certain rules which are universal. They are unique and can be used to identify an organism anywhere around the world. That is why, scientific names of living beings are considered better than their common names.
4. Mention any two drawbacks in classifying organisms under the old two kingdom classification.
Solution C.4.
According to the ‘Two-Kingdom Classification’, proposed by Carolus Linnaeus in 1758, living organisms were classified into two broad kingdoms, Plants and Animals.
The drawbacks in classifying organisms under the old two kingdom classification are:
1. Bacteria were kept in Kingdom Plantae. These organisms have no chlorophyll and do not carry out photosynthesis. Bacteria do not have a definite nucleus nor a nuclear membrane nor chromosomes.
2. Fungi were kept in Kingdom Plantae. Bread mould is a multicellular fungi. However, it does not possess roots, stem and leaves, lacks chlorophyll and does bear any flowers, fruits and seeds like plants.
5. All humans on earth today may differ widely in their facial features, colour, height, etc. Yet, they belong to a single species Homo sapiens. Give one reason why they are not considered belonging to different species.
Solution C.5.
Species means an organism of a particular kind whose members can interbreed among themselves to produce fertile young ones.
All humans on the earth today may differ widely in their facial features, colour, height, etc. Yet, they belong to a single species Homo sapiens because they can interbreed among themselves and produce a normal offpsring.
6. Rewrite the following scientific names correctly.
ficus religiosa (peepal), zea Mays (maize) and Bombyx Mori (silk moth).
Solution C.6.
Ficus religiosa (Peepal)
Zea mays (Maize)
Bombyx mori (Silkmoth)
7. Name the five kingdoms according to the new classification.
Solution C.7.
The five kingdoms according to the new classification are:
1. Kingdom Monera
2. Kingdom Protista
3. Kingdom Fungi
4. Kingdom Plantae
5. Kingdom Animalia
8.What are the group names of the following categories of animals?
(a) Animals with a backbone _____________
(b) Animals with a hairy skin ___________
(c) Animals with three pairs of legs ___________
(d) Animals with feathers _________
Solution C.8.
(a) Animals with a backbone: Vertebrata
(b) Animals with a hairy skin: Mammalia
(c) Animals with three pairs of legs: Insecta
(d) Animals with feathers: Aves

Solution C.12.
13. Name three animals (belonging to different classes) which breathe by means of lungs but have no external ears (pinnae).
Solution C.13.

2. Match the names of animal groups in Column I with the names of animals in column II.
Column I (Group)
|
Column II (Animals)
|
Annelida
|
Pigeon
|
Porifera
|
Snake
|
Mollusca
|
Earthworm
|
Reptilia
|
Sponge
|
Amphibia
|
Octopus
|
Pisces
|
Trout
|
Mammal
|
Rabbit
|
Which names are left out that do not match and why?
Amphibia from Column I and Pigeon from column II are left out. They do not match as Pigeon comes under Class Aves and not Class Amphibia.
E. Skill Types
1.TYRANNOSAURUS
(One of the extinct animals which lived on the Earth about 100,000,000 years ago) Tyrannosaurus was about six metres long and it preyed upon other animals.
What do you think about its classification-was it an amphibian, a reptile or a mammal?
Can you call it a relative of Kangaroo? Yes/No. Give reason
Solution E.1.
No, it is not a relative of Kangaroo as Kangaroo is a mammal and Tyrannosaurus is a reptile.
Characteristics of Tyrannosaurus:
1. Body has scales which may be horny
2. Lays eggs which have a leathery shell
3. One of the dinosaurs which moved on the earth. These ruled the earth. Some were vegetarian, others were non-vegetarian. Archaeopteryx is a link between reptiles and birds. Its fossils have been found, which vanished from the earth due to ice-age.
4. Had three-chambered heart as ventricles are partially divided
5. Cold-blooded animals
