Exercise 6.1 page: 69

1. What is a handkerchief?

Solution:

A tissue is defined as a cluster of cells that are structurally similar and work together to perform a specific function.

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

Solution:

Tissues are used in multicellular organisms to provide structural and mechanical strength as well as to enable division of labor.

Exercise 6.2 page: 73

3. Name the types of simple tissues.

Solution:

The types of plain weaves are as follows:

➢ Parenchyma

➢ Collenchym

➢ Sklerenchym

4. Where is apical meristem found?

Solution:

In plants, apical meristems are typically found at:

• The tip of the shoot
• root of the plant

5. What tissue is the shell of a coconut made of?

Solution:

The sclerenchymal tissue, a type of permanent tissue, forms the shell of the coconut. This tissue causes the plant to become stiff and hard. The cells of this tissue are dead and their cell walls are thickened due to the presence of lignin.

6. What are the components of phloem?

Solution:

The phloem consists of the following four elements:

➢ Screen tube

➢ Companion cells

➢ Phloemparenchym

➢ Phloem fibers

Exercise 6.3 page: 77

7. Name the tissues responsible for the movement of our body.

Solution:

Two tissues are jointly responsible for the movement of our body, namely:

➢ Muscle tissue

➢ Nerve tissue

8. What does a neuron look like?

Solution:

A neuron is a nerve cell consisting of the cell body with nucleus and cytoplasm, which gives rise to a long and thin hair-like structure. Each neuron has an elongated part known as the axon and several short and small branched structures known as dendrites. A single neuron can be as long as a meter.

9. Give three characteristics of heart muscles.

Solution:

Heart muscles are specialized tissues designed to pump blood around the body.

The following are the characteristics of cardiac muscles:

➢ They have a cylindrical shape.

➢ Striated muscle fibers.

➢ They are seedless and branched.

➢ These muscles are involuntary in nature.

10. What are the functions of areolar tissue?

Solution:

Areolar tissues are typically observed in animals. They are connective tissue and are located between the skin and muscles. They are also found around blood vessels and nerves and are present in the bone marrow. The space inside the organs is filled with these tissues. They support the sensitive internal organs and help with tissue repair in the event of damage.

Exercise page: 78

1. Define the term "tissue".

Solution:

A tissue is defined as a cluster of cells that are structurally similar and work together to perform a specific function.

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

Solution:

The xylem tissue consists of four main elements, namely:

➢ Ships

➢ Tracheids

➢ Xylem fibers

➢ Xylemparenchym

3. How do simple tissues differ from complex tissues in plants?

Solution:

Below are the differences:

4. Distinguish parenchyma, collenchyma and sclerchyma based on their cell wall.

Solution:

The following are the differences between different tissues based on cell wall:

5. What are the functions of the stomata?

Solution:

Stomata are the tiny pores present on the outer layer of cells, the epidermis. Stomata cause gas exchange and transpiration.

6. Diagram the difference between the three types of muscle fibers.

Solution:

There are three types of muscle fibers:

1. Heart muscles

• present in the heart.
• Involuntary nature.
• You have 1 core.
• The muscle fibers are branched.

2. Smooth muscle

• Found in the lungs and alimentary canal.
• Involuntary nature.
• You have 1 core.
• They are spindle shaped.

3. Striated muscles

• They are connected to bones
• Voluntary nature.
• They are long and cylindrical muscle fibers.
• They have many cores.
• Striated muscles are unbranched.

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

Solution:

The cardiac muscles are branched and cylindrical. They are seedless and involuntary in nature. The heart muscles cause a rhythmic contraction and relaxation throughout life.

8. Distinguish between striated, non-striated, and cardiac muscles based on their structure and location in the body.

Solution:

Below are the differences between different muscle types based on their structure and location in the body.

9. Draw a labeled diagram of a neuron.

Solution:

Diagram of a neuron along with the labeling is as follows:

10. Name the following.

(a) Tissue that forms the inner lining of our mouth.

(b) Tissue connecting muscle to bone in humans.

(c) tissue that transports food in plants.

(d) Tissues that store fat in our body.

(e) connective tissue with a fluid matrix.

(f) Tissue present in the brain.

Solution:

(a) Tissue that forms the inner lining of our mouth - the epithelial tissue, squamous epithelium.

(b) Tissue connecting muscle to bone in humans - tendon

(c) Tissue that transports food in plants - phloem

(d) Tissue that stores fat in our body – adipose tissue

(e) Fluid Matrix Connective Tissue - Blood, it is a fluid connective tissue

(f) Tissue present in the brain - nerve tissue

11. Identify the type of tissue below:

Skin, tree bark, bones, lining of renal tubules, vascular bundles.

Solution:

➢ Skin: Stratified squamous tissue

➢ Tree bark: protective fabric and cork

➢ Bone: connective tissue

➢ Lining of the renal tubule: cuboidal epithelial tissue

➢ Vascular bundles: conductive tissue (xylem and phloem), complex permanent tissue

12. Name the regions where parenchymal tissue is present.

Solution:

The parenchyma is found in:

• The pith of the stems and roots
• When the parenchyma contains chlorophyll, it is called chlorenchyma. It is found in green leaves
• The parenchyma found in aquatic plants has large air cavities that allow them to swim and is therefore called aerenchyma.

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

Solution:

The epidermis in plants forms an uninterrupted and continuous layer that has no intercellular spaces. It offers protection.

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

Solution:

Cork cells are dead. The arrangement of the cells is so dense that there is no intercellular space. A deposit of suberin is observed on the walls of the cells, making them impermeable to water and gases.

15. Complete the following table.

Solution:

The finished diagram looks like this:
