Short Answer Type

Question 1

Rearrange the following categories of classification in their proper sequence starting with the highest.

species, family, genus, class, order, phylum.

Answer

Phylum → Class → Order → Family → Genus → Species

Question 2

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

Answer

Man — Homo sapiens

Domestic cat — Felis domesticus

Peepal tree — Ficus religiosa

Question 3

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

Answer

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.

Question 4

Mention any two drawbacks in classifying organisms under the old two kingdom classification.

Answer

Carolus Linnaeus In 1758, anciently divided all living organisms into two kingdoms : The drawbacks of this 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.

Question 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.

Answer

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.

Question 12

Explain the meaning of the terms cold-blooded and warm-blooded (homeothermal).

Answer

Cold-blooded animals — These animals cannot maintain their body temperature. Their body temperature fluctuates directly with the temperature of the environment. Animals of classes Pisces, Amphibia, Reptilia are cold-blooded animals.

Warm-blooded animals (homeothermal) — These animals maintain an almost constant, relatively high body temperature irrespective of the temperature of the environment. Animals of classes Aves and Mammalia are warm-blooded or homeothermal animals.

Question 13
