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

Phylum → Class → Order → Family → Genus → Species

2. Give the scientific names of man, domestic cat, and peepal tree.

Solution

• Man: Homo sapiens
• Domestic cat: Felis domesticus
• Peepal tree: Ficus religiosa

 

3. Why are scientific names of living beings considered better than their common names?

Solution

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 of classifying organisms under the old kingdom classification.

Solution

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:

(i) 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.
(ii) 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

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 offspring.

 

6. Rewrite the following scientific names correctly.
ficus religiosa(peepal), zea Mays (maize) and Bombyx Mori (silk moth).

Solution

• Ficus religiosa (Peepal)
• Zed mays (Maize)
• Bombyx mori (Silkmoth)

E Structured/Application/Skill Type

1. 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

Tyrannosaurus is a reptile while Kangaroo is a mammal, hence they are not related to each other.

Features of Tyrannosaurus:

• Cold-blooded animals.
• Presence of scales throughout the body which can be horny.
• They are egg-laying animals. The eggs possess a leathery shell.
• Possessed three chambered heart as the ventricles were divided partially.
• Dinosaurs reigned the earth back then, few were vegetarian while few others were non-vegetarians.
