Solutions for Biology, Class 9, ICSE

Assertion Reason Type

6 questions

Question 2(i)

Assertion (A): Monera and Protista are similar with respect to their number of cells. Both are unicellular.

Reason (R): They differ with respect to their nuclei. Monerans are prokaryotic and protists are eukaryotic.

  1. A is True and R is False.
  2. A is False and R is True.
  3. Both A and R are True.
  4. Both A and R are False.
Assertion Reason Type

Answer:

Both A and R are True.

Reason — Both Monera and Protista are unicellular organisms. They differ in type of nuclei, Monerans are prokaryotic (no true nucleus or membrane-bound organelles) while Protists are eukaryotic (have a well-defined nucleus and organelles).

Question 2(ii)

Assertion (A): Gymnosperms are flowering plants which bear naked seeds.

Reason (R): Gymnosperms bear seeds in cones.

  1. A is True and R is False.
  2. A is False and R is True.
  3. Both A and R are True.
  4. Both A and R are False.
Assertion Reason Type

Answer:

A is False and R is True.

Reason — Gymnosperms are not flowering plants. They are non-flowering seed plants that bear naked seeds. Gymnosperms bear seeds in cones.

Question 2(iii)

Assertion (A): Jungle crow and house crow can breed among themselves as both belong to the same genus.

Reason (R): They can interbreed among themselves as both are crows and only their habitat is different.

  1. A is True and R is False.
  2. A is False and R is True.
  3. Both A and R are True.
  4. Both A and R are False.
Assertion Reason Type

Answer:

Both A and R are False.

Reason — As jungle crow (Corvus macrorhynchos) and house crow (Corvus splendens) belong to different species they cannot interbreed. Their inability to interbreed is not due to their differing habitats only.

Question 2(iv)

Assertion (A): Ostia are the openings in the body wall of sponges through which water enters inside the body.

Reason (R): Osculum is a mouth-like structure on the top of the sponge's body through which water is thrown out.

  1. A is True and R is False.
  2. A is False and R is True.
  3. Both A and R are True.
  4. Both A and R are False.
Assertion Reason Type

Answer:

Both A and R are True.

Reason — Ostia are tiny pores present all over the body of a sponge. They allow water to enter the body, bringing in oxygen and food particles. The osculum is a large opening at the top of the sponge. It is the exit point for water after circulation through the sponge’s body.

Question 2(v)

Assertion (A): Clitellum is the glandular skin which surrounds the body of an earthworm at its posterior end.

Reason (R) : Clitellum serves in reproduction.

  1. A is True and R is False.
  2. A is False and R is True.
  3. Both A and R are True.
  4. Both A and R are False.
Assertion Reason Type

Answer:

A is False and R is True.

Reason — The clitellum is a glandular, thickened region of the skin in earthworms, but it is located near the anterior (front) end, not the posterior end. The clitellum plays a crucial role in reproduction

Question 2(vi)

Assertion (A): Both Pisces and Amphibians have a two chambered heart.

Reason (R): As pisces are the most primitive chordates, they only have a one chambered heart. Amphibians are little advanced than pisces, so they have a two chambered heart.

  1. A is True and R is False.
  2. A is False and R is True.
  3. Both A and R are True.
  4. Both A and R are False.
Assertion Reason Type

Answer:

Both A and R are False.

Reason — Pisces have a two-chambered heart while amphibians have a three-chambered heart.
Pisces do not have a one-chambered heart — they have two chambers and amphibians are more evolved and have three chambers, not two.

Question 2

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

Long Answer Type

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 8

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

Short Answer Type

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.

Short Answer Type

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 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.

Short Answer Type

Answer:

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