Test: Tissues- Assertion & Reason Type Questions - Question 1
Save

Direction: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:

Assertion: Bark of trees are impervious to gases and water.

Reason: Cells of bark have suberin in their walls.

Detailed Solution for Test: Tissues- Assertion & Reason Type Questions - Question 1
Cells of bark are dead and compactly arranged without intercellular spaces. They have a chemical called suberin in their walls that make them impervious to gases and water.

Direction: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:

Assertion : Vessel and sieve tube both are meant for transport purposes.

Reason : Vessels are lignified.

Detailed Solution for Test: Tissues- Assertion & Reason Type Questions - Question 2

Let's analyze the assertion and the reason:

Assertion (A): Vessel and sieve tube both are meant for transport purposes.

  • This statement is true. Vessels are involved in the transport of water and minerals in plants (part of the xylem), while sieve tubes are involved in the transport of food (sugars) in plants (part of the phloem).

Reason (R): Vessels are lignified.

  • This statement is also true. Vessels are lignified, meaning they have thickened cell walls reinforced with lignin, which provides structural support and helps in the efficient transport of water.

However, the reason (R) given does not directly explain the assertion (A). The fact that vessels are lignified does not explain why both vessels and sieve tubes are meant for transport purposes.

Correct Answer:

2 (Both assertion (A) and reason (R) are true, but reason (R) is not the correct explanation of assertion (A)).

Direction: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:

Assertion: Guard cells are specialized epidermal cells.

Reason: Stomata are found in the epidermis of leaves.

Detailed Solution for Test: Tissues- Assertion & Reason Type Questions - Question 3
Stomata are present in the epidermis of leaves. They are essential for transpiration and gaseous exchange. Stomata are minute aperture bounded by two specialized epidermal cells called guard cells.
Test: Tissues- Assertion & Reason Type Questions - Question 4

Direction: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:

Assertion : Lateral meristems add thickness of plants.

Reason : Lateral meristems divide only in one plane.
Detailed Solution for Test: Tissues- Assertion & Reason Type Questions - Question 4
Lateral meristems are present along the side of the stem. Vascular cambium in the gymnosperms and the angiosperms is a good example of lateral meristems. Lateral meristem is always composed of a single layer of rectangular cells that divide only in one plane and produce new vascular tissues on either side.
Test: Tissues- Assertion & Reason Type Questions - Question 5
Save

Direction: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:

Assertion: Permanent tissue is composed of mature cells.

Reason: Meristematic tissue is a group of actively dividing cells.
Detailed Solution for Test: Tissues- Assertion & Reason Type Questions - Question 5
Meristematic tissues are made up of actively dividing cells, present in the growing areas of the plant body whereas Permanent tissue is a well-differentiated plant tissue derived from meristematic tissue, which has lost its ability to divide.
Test: Tissues- Assertion & Reason Type Questions - Question 6
Save

Direction: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:

Assertion : Surface of skin is impervious to water.

Reason : Surface of skin is covered by stratified cuboidal epithelium.
Detailed Solution for Test: Tissues- Assertion & Reason Type Questions - Question 6
Surface of skin is impervious to water because it is covered by stratified keratinized squamous epithelium. This epithelium has many superficial layers of horny, scale- like remains of dead squamous cells and several deeper layers of living polygonal cells. Heavy deposits of the insoluble protein keratin are present in the dead superficial layers which makes this epithelium impervious to water. Stratified cuboidal epithelium, on the other hand, lines the inner surface of sweat gland, large salivary and pancreatic ducts.

Direction: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:

Assertion: Husk of coconut is made of sclerenchymatous tissue.

Reason: Cells of sclerenchymatous tissue are dead with long and narrow walls thickened due to lignin.
Detailed Solution for Test: Tissues- Assertion & Reason Type Questions - Question 7
Husk of coconut is made of sclerenchymatous tissue. The cells are dead with long and narrow walls thickened due to lignin.
Test: Tissues- Assertion & Reason Type Questions - Question 8
Save

Direction: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:

Assertion : Meristematic tissues constitute the major portion of the plant body.

Reason : Meristematic tissues consist of differentiated cells.
Detailed Solution for Test: Tissues- Assertion & Reason Type Questions - Question 8

Meristematic tissues, after differentiation, give rise to permanent tissues. These constitute the major portion of the plant body.

 1 A plant is composed of two main types of tissue: meristematic tissue and permanent tissue. Meristematic tissue consists of actively dividing cells found in root and shoot tips. As growth occurs, meristematic tissue differentiates into permanent tissue, which is categorized as either simple or complex.

 2 Meristematic tissue cells are either undifferentiated or incompletely differentiated, and they continue to divide and contribute to the growth of the plant. ... Such cells take on specific roles and lose their ability to divide further. They differentiate into three main types: dermal, vascular, and ground tissue.

Direction: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:

Assertion: Bone and cartilage are connective tissue.

Reason: Blood is connective tissue in which plasma is the matrix.
Detailed Solution for Test: Tissues- Assertion & Reason Type Questions - Question 9

- Assertion (A): True. Bone and cartilage are types of connective tissue. They support and protect the body, with bone being hard and rigid, while cartilage is more flexible.
- Reason (R): True. Blood is indeed a connective tissue, and the plasma serves as its matrix, providing a medium for transporting nutrients, waste, and cells.
- The reason does not explain why bone and cartilage are connective tissues; it describes blood instead.

Thus, the correct choice is A: Both assertion and reason are true, but reason is not the correct explanation of assertion.

Test: Tissues- Assertion & Reason Type Questions - Question 10
Save

Direction: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:

Assertion : Ciliated epithelium helps in movement of particles.

Reason : Cilia help in movement.
Detailed Solution for Test: Tissues- Assertion & Reason Type Questions - Question 10
The function of the cilia is to move particles, free cells or mucus in a specific direction. It is present in inner surfaces of some hollow organs such as Fallopian tubes, bronchioles and small bronchi and help in movement of the particles present there. Thus, the function of ciliated epithelium (as it possesses cilia) is the movement of particles.
