Question 1.

Name these:

(a) Five kingdoms under the recent scheme of classification.

(b) Five divisions of kingdom Plantae.

(c) Eight phyla of Invertebrates.

(d) Five classes of Chordata.

(e) Two types of fishes on the basis of their skeletons.

Answer:

(a) The five kingdoms according to the new classification are:

  • Kingdom Monera
  • Kingdom Protista
  • Kingdom Fungi
  • Kingdom Plantae
  • Kingdom Animalia

(b) Five divisions of kingdom Plantae are:

  • Thallophyta
  • Bryophyta
  • Pteridophyta
  • Gymnosperms
  • Angiosperms

(c) Eight phyla of Invertebrates are:

  • Porifera
  • Cnidaria
  • Platyhelminthes
  • Nematoda
  • Annelida
  • Arthropoda
  • Mollusca
  • Echinodermata

(d) Five classes of Chordata are:

  • Pisces
  • Amphibia
  • Reptilia
  • Aves
  • Mammalia

(e) Two types of fishes on the basis of their skeletons are:

  • Cartilaginous fishes
  • Bony fishes

Question 2.

Define the terms:

(a) Species

(b) Clitellum

(c) Moulting

(d) Diaphragm

(e) Nocturnal animals

Answer:

(a) Species — Species means an organism of particular kind whose members can interbreed among themselves to produce fertile young ones.

(b) Clitellum — The clitellum is a specialized reproductive structure found in certain annelids, particularly in earthworms. It is a short cylindrical band of thick glandular skin that surrounds the body like a belt and is around one-third distance of the body from the front end in the segments 14-16.

(c) Moulting — The casting off and the regrowing of the exoskeleton is collectively called moulting. It occurs in Arthropods.

(d) Diaphragm — A muscular structure separating thorax and abdomen internally in mammals is called diaphragm.

(e) Nocturnal animals — Animals that are active during night are known as nocturnal animals.

Question 3.

Write the specific location and function of:

(a) Microscopic spicules or elastic spongin fibre

(b) Tentacles

(c) Parapodium

(d) Fins

(e) Feathers

Answer:

(a) Microscopic spicules or elastic spongin fibre.
Location — It forms the skeleton of Sponges.
Function — Structural support and defense against predators.

(b) Tentacles
Location — around mouth in Coelentrates.
Function — To catch food organisms.

(c) Parapodium
Location — Found in certain marine annelids. Usually located on either side of a segment, extending outward from the body wall. Function — Locomotion.

(d) Fins
Location — Found in Class Pisces (Fishes) organisms. They have fins instead of limbs.
Function — Swimming.

(e) Feathers
Location — Found in Class Aves (Birds) organisms. They have an exoskeleton of feathers.
Function — To facilitate flying.

Question 4.

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 5.

Rewrite the following scientific names correctly.

ficus religiosa (peepal), zea Mays (maize) and Bombyx Mori (silk moth).

Answer:

Ficus religiosa (Peepal)

Zea mays (Maize)

Bombyx mori (Silkmoth)

(Five Kingdom Classification Short Answer Class-9 ICSE)

Question 6.

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?

Answer:

Column I Column II
Annelida Earthworm
Porifera Sponge
Mollusca Octopus
Reptilia Snake
Pisces Trout
Mammal Rabbit

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.

Question 7.

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

Answer:

Man Domestic
cat
Peepal
tree
Homo
sapiens
Felis domesticus Ficus
religiosa 

 

Question 8.

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 9.

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

Answer:

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:

  • Bacteria were kept in Kingdom Plantae. These organism shave no chlorophyll and do not carry out photosynthesis. Bacteria do not have a definite nucleus nor a nuclear membrane nor chromosomes.
  • 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 10.

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 off spring.

Question 11.

Give any one difference between each of the following :

(a) Insecta and Arachnida,

(b) Flatworm and Roundworm,

Answer:

(a) difference between Insecta and Arachnida
Insecta Arachnida

pairs of legs

 

(b) difference between Flatworm and Roundworm
Flatworm Roundworm
Dorso-ventrally flattened Cylindrical in

shape and are

tapered at

both ends
