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

Solution: The following are the differences:

• Simple tissues: These are composed of a single type of cell that performs a specific function. Examples include parenchyma, collenchyma, and sclerenchyma in plants, each serving roles like storage, support, or protection.

• Complex tissues: These involve multiple types of cells working together to perform specialized functions. For instance, xylem and phloem in plants coordinate to transport water, nutrients, and organic substances throughout the plant.

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

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

Parenchyma:

• Cell walls are thin and primarily made up of cellulose.

• These tissues are often involved in functions like photosynthesis, storage, and secretion.

Collenchyma:

• Cell walls are thicker at the corners due to the deposition of pectin.

• They provide flexible structural support to young parts of the plant, such as stems and petioles.

Sclerenchyma:

• Cell walls are very thick due to the deposition of lignin, making them rigid and strong.

• These tissues provide mechanical support and protection to mature parts of the plant, such as the seed coats and vascular bundles.

Ques. 5. What are the functions of the stomata?

Solution: Stomata are small pores found on the outer layer (epidermis) of leaves and stems of plants. They play several important roles:

• Gas Exchange: Stomata allow for the exchange of gases, such as oxygen and carbon dioxide, between the plant and its environment. This process is crucial for photosynthesis (uptake of carbon dioxide) and respiration (release of oxygen).

• Transpiration: Stomata also regulate the process of transpiration, where water vapor exits the plant through these pores. This helps in cooling the plant and maintaining its internal water balance.

Ques. 6. Show the difference between the three types of muscle fibres diagrammatically.

Solution: There are three types of muscle fibres, they are: 1. Cardiac muscles

• Present in the heart.

• Involuntary in nature.

• They have 1 nucleus.

• The muscle fibers are branched.

2. Smooth muscles

• Found in lungs and alimentary canal.

• Involuntary in nature.

• They have 1 nucleus.

• They are spindle-shaped.

3. Striated muscles

• They are connected with bones

• Voluntary in nature.

• They are long and cylindrical muscle fibers.

• They possess many nuclei.

• Striated muscles are unbranched.

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

Solution: Cardiac muscles are characterized by their branched and cylindrical shape. They are uninucleated and function involuntarily, meaning they contract and relax rhythmically throughout an individual's lifetime. These muscles are essential for maintaining the continuous pumping action of the heart, which circulates blood throughout the body, supplying oxygen and nutrients to tissues and organs while removing metabolic waste products.
