NCERT Solutions for Class 9 Science Chapter 6 - Tissues

Intext Questions:

1. What is a tissue?

Ans: Tissue is a collection of cells with comparable structures that are placed in order to fulfill a given activity.

2. What is the utility of tissues in multicellular organisms?

Ans: Tissues in multicellular organisms are differentiated to perform a specific function at a given location, a process known as division of labor. Nerve cells, for example, make up the neurological tissue that aids in message transmission, whereas muscular cells make up the muscle tissue and muscle tissue is a type of tissue that aids in movement.

3. Name the types of simple permanent tissues

Ans: Parenchyma, Collenchymas, and Sclerenchyma are the three forms of simple permanent tissues. Aerenchyma and chlorenchyma are two types of parenchyma tissue.

4. Where is apical meristem found?

Ans:  At the growing tips of stems and roots, the apical meristem is present.

5. Which tissue makes up the husk of coconut?

Ans: Sclerenchyma tissue is a form of simple permanent tissue that makes up the husk of the coconut.

6. What are the constituents of phloem?

Ans: The food-conducting tissue of plants is termed as phloem. Sieve tubes, Companion cells, Phloem parenchyma, and Phloem fibers are the four components.

7. Name the tissue responsible for movement in our body.

Ans: Muscle Tissues are responsible for movement.

8. What does a neuron look like?

Ans: A neuron is made up of three parts: the cell body, the axon, and the dendrites. Dendrites are a significant number of extensions that stretch outward from the cell body and resemble branches. A nucleus and other cell organelles make up the cell body. An axon is a tube-like structure that transports an electrical impulse from the cell body to the neuron's opposite end structures.

9. Give three features of cardiac muscles.

Ans:  Features of cardiac muscles:

• They are involuntary in nature.

• They are cylindrical, branched, and uninucleate in structure.

• Throughout their lives, they exhibit cyclic contraction and relaxation.

10. What are the functions of areolar tissue?

Ans: Areolar tissues are commonly seen in animals. They are connective tissues that exist between the skin and the muscles. They can also be found in the bone marrow and around blood arteries and nerves. These tissues take up a lot of room inside the organs. They protect the internal organs and aid in tissue restoration in the event of harm.

Exercise

1. Define the term “tissue”.

Ans:  A tissue is described as a group of cells with identical structures that collaborate to execute a certain purpose.

2. How many types of elements together make up the xylem tissue? Name them.

Ans: The xylem tissue is made up of four main elements as mentioned :

• Vessels

• Tracheids

• Xylem fibers

• Xylem parenchyma

3. How are simple tissues different from complex tissues in plants?

Ans:

4. Differentiate between parenchyma, collenchyma, and sclerenchyma, on the basis of their cell wall.

Ans:

5. What are the functions of the stomata?

Ans: Stomata functions include the exchange of gases with the atmosphere. The stomata are responsible for transpiration.

6. Diagrammatically show the difference between the three types of muscle fibres.

Ans: Striated muscles, smooth muscles (unstriated muscle fibre), and cardiac muscles are the three types of muscular fibres.

Striated Muscle cells

Smooth muscle cells

Cardiac muscle cells

7. What is the specific function of the cardiac muscle?

Ans: The cardiac muscle is responsible for controlling the heart's contraction and relaxation.

8. Differentiate between striated, unstriated, and cardiac muscles on the basis of their structure and site/location in the body.

Ans: Differences between striated, unstriated and cardiac muscles are:

9. Draw a labeled diagram of a neuron.

Ans:

Structure of Neuron

10. Name the following:

1. Tissue that forms the inner lining of our mouth. 

Ans: Epithelial tissue 

2. Tissue that connects muscle to bone in humans. 

Ans: Dense regular connective tissue (tendons)

3. Tissue that transports food in plants. 

Ans: Phloem 

4. Tissue that stores fat in our body. 

Ans: Adipose tissue 

5. Connective tissue with a fluid matrix. 

Ans: Blood

6. Tissue present in the brain.

Ans: Nervous tissue

11. Identify the type of tissue in the following: skin, the bark of a tree, bone, lining of kidney tubule, vascular bundle.

 Ans: 

• Skin: Stratified squamous epithelial tissue

• The Bark of a Tree: Simple permanent tissue

• Bone: Connective tissue

• The Lining of Kidney Tubule: Cuboidal epithelial tissue

•  Vascular Bundle: Complex permanent tissue

12. Name the regions in which parenchyma tissue is present.

 Ans: Leaves, fruits, and flowers.

13. What is the role of the epidermis in plants?

Ans: Role of the epidermis:

• Protection of different parts of the plant.

• Epidermal cells present in roots, help in the absorption of water.

• For protection against loss of water, mechanical injury, and parasitic fungus by producing a waxy, water-resistant covering called the cuticle, which is made of cutin, on the outer surface of the plant.

14. How does the cork act as a protective tissue?

Ans: The cork, which is made up of dead cells, is the bark of a tree. It protects the plant from mechanical damage and temperature extremes, as well as it prevents water loss through evaporation.

15. Complete the table:

Ans:

Class 9 Science Chapter 6 Quick Overview of Detailed Structure of Topics

Class 9 Chapter 6 Science - Tissues - Important Points

• Tissues are groups of cells with similar structures and functions. They work together to perform specific tasks in an organism.

• Plant Tissues: Plant tissues are categorised into two types:

• Meristematic Tissues: These tissues are responsible for the growth of the plant. They are found at the tips of roots and shoots.

• Permanent Tissues: These tissues are further classified into three types:

• Simple Permanent Tissues: Parenchyma, Collenchyma, and Sclerenchyma

• Complex Permanent Tissues: Xylem and Phloem

• Animal Tissues: Animal tissues are categorised into four types:

• Epithelial Tissue: Covers the body surfaces, lines the body cavities, and forms glands.

• Connective Tissue: Provides support, protection, and structure to the body. Examples include bone, cartilage, blood, and adipose tissue.

• Muscular Tissue: Responsible for movement. There are three types: skeletal, smooth, and cardiac muscle.

• Nervous Tissue: Transmits and receives nerve impulses. It consists of neurons and neuroglia.

• Functions:

• Plant tissues are mainly involved in providing support, conducting water and nutrients, storage, and photosynthesis.

• Animal tissues perform various functions such as protection, support, movement, and coordination of body activities.
