Why is there no demarcation of dividing and non-dividing regions in animals?

  1. Animals are symmetrical.

  2. Cell growth is uniform in animals.

  3. Movement in animals is uniform.

  4. Most of the tissues are dead in animals.

  5. None of these

Show answer
Correct Option: B
Explanation:

Yes, it is correct. Cell growth in animals is more uniform and so, there is no such demarcation of dividing and non-dividing regions in animals.

Plant tissues in which cells keep on dividing are called meristematic tissues, one of which is apical meristem. Where is this tissue present?

  1. Root apex and stem apex

  2. Flower buds

  3. Leaf buds

  4. Both (2) and (3)

  5. All of the above

Show answer
Correct Option: E
Explanation:

Yes, it is correct. The apical meristem is responsible for primary growth and so, it is present in all of the above parts of a plant.

Why do animals consume more energy than plants?

a. Plants are stationary and animals move around. b. Animal body is bulkier than plant body. c. Most of the tissues in plants are dead, unlike animals. d. Structural organisation of organs in animals is more specialised.

  1. Only a and d

  2. Only a and c

  3. Only b and c

  4. Only b and d

  5. Only c and d

Show answer
Correct Option: B
Explanation:

Yes, it is correct. Both 'a' and 'c' are correct statements. Plants are stationary and they do not move. Most of the plant tissues are dead and need less maintenance. Hence, animals consume more energy than plants.

Which of the following statements regarding the meristematic tissues is false?

  1. They have dense cytoplasm.

  2. They have big vacuoles.

  3. Lateral meristem is responsible for growth in the girth.

  4. They are of three types.

  5. None of these

Show answer
Correct Option: B
Explanation:

Yes, it is the correct answer. Vacuoles are absent in the meristematic tissues.

In which of the following tissues can the differentiation process be seen?

  1. Complex permanent tissue

  2. Parenchyma tissue

  3. Meristematic tissue

  4. Collenchyma tissue

  5. None of these

Show answer
Correct Option: C
Explanation:

Yes, it is correct. After differentiation in the meristematic tissue, the cells lose their capability to divide and the tissues become permanent tissues. 

Which of the following parenchyma tissues has chlorophyll and carries out photosynthesis?

  1. Aerenchyma

  2. Collenchyma

  3. Chlorenchyma

  4. Sclerenchyma

  5. None of these

Show answer
Correct Option: C
Explanation:

Yes, it is correct. The parenchyma tissue having chlorophyll and that carries out photosynthesis is chlorenchyma.

The opening and closing of stoma is controlled by two guard cells, which are

  1. leaf-shaped

  2. kidney-shaped

  3. circular in shape

  4. finger-shaped

  5. None of these

Show answer
Correct Option: B
Explanation:

Yes, it is correct. The shape of each guard cell of a stoma is like a kidney.

In which of the following elements of the vascular tissue are the cells dead?

  1. Sieve tube

  2. Tracheids

  3. Companion cells

  4. Phloem fibres

  5. All of the above

Show answer
Correct Option: B
Explanation:

Yes, it is correct. The tracheids are present in xylem. The cells have thick walls and are dead cells.

Coconut husk is an example of which of the following tissues?

  1. Sclerenchyma

  2. Collenchyma

  3. Chlorenchyma

  4. Aerenchyma

  5. None of these

Show answer
Correct Option: A
Explanation:

Yes, it is correct. The cells here are dead and intercellular space is absent. It presents structural rigidity to plant parts. Coconut husk is an example of this tissue.

In which of the following parts is the soft connective tissue having widely spaced cells not present?

  1. Ears

  2. Nose

  3. Trachea

  4. Arms

  5. None of these

Show answer
Correct Option: D
Explanation:

Yes, it is correct. Arms have bones, not soft cartilages. One can fold the cartilages of the ears, but not the bones in the arms.

Where is the areolar connective tissue not found?

  1. Beneath the dermis layer

  2. In the bone marrow.

  3. It is a component of the lamina propria of the digestive and respiratory tracts.

  4. It is a key component of membranes.

  5. All of the above

Show answer
Correct Option: B
Explanation:

No, it is incorrect. The areolar tissue is not  found in bone marrow..

Which of the following characteristics do the muscles of the iris of human eye not have?

  1. The cells are long with pointed ends.

  2. They have a single nucleus.

  3. They are unstriated.

  4. They are involuntary.

  5. None of these

Show answer
Correct Option: E
Explanation:

Yes, it is correct. The muscles of iris are the smooth muscles or involuntary muscles. They have all of the above characteristics. Hence, this option is correct.

Why is blood called a connective tissue?

a. It carries food and oxygen to all the cells. b. It connects bones and muscles. c. It collects waste from all the parts of the body to liver and kidney. d. It connects bones to bones.

  1. Only a and b

  2. Only c and b

  3. Only a and c

  4. Only b and d

  5. None of these

Show answer
Correct Option: C
Explanation:

Yes, it is correct. Both 'a' and 'c' are true. Blood carries food and oxygen to all the cells. It also collects waste from all the parts of the body and carries it to liver and kidney.

Which of the following parts of a neuron receives the nerve impulse?

  1. Cyton

  2. Dendrites

  3. Axon

  4. Nucleus

  5. None of these

Show answer
Correct Option: B
Explanation:

Yes, it is correct. Dendrites receive the nerve impulses and transfer it to the cell body.

Which of the following is not a type of the epithelial tissue that forms the covering or lining of most of the organs?

  1. Areolar

  2. Simple

  3. Cuboidal

  4. Stratified

  5. Columnar

Show answer
Correct Option: A
Explanation:

Yes, it is correct. Areolar tissue is a type of connective tissue, and not epithelial tissue. Areolar tissue is found between skin and muscles, around blood vessels and nerves and in the bone marrow.
