Class 9 Biology Worksheet for Tissues

 

Very Short Answer Type Questions

Question. What do you mean by aerenchyma?
Answer : Aerenchyma is the cell with large air-filled cavities of parenchyma. It helps aquatic plants to float.

Question. Name the tissues which are present in the plants at the nodes.
Answer : Intercalary tissues.

Question. What is the location of stratified squamous epithelium? Also, mention its functions.
Answer : Stratified squamous epitheliums are found in the skin. They are present in layers to prevent wear and tear.

Question. Which tissue is present in the husk of a coconut?
Answer : Sclerenchyma.

Question. Which tissue gives flexibility in plants?
Answer : Collenchyma.

Question. Define tracheids.
Answer : Tracheids have tapering ends and are basically elongated cells.

Question. What is a tissue?
Answer : Group of cells that are similar in structure and are organized together to achieve a particular function is called tissue.

Question. Which tissue makes up the husk of coconut?
Answer :
 The husk of coconut is made up of sclerenchymatous tissue.

Question. Name the tissue responsible for movement in our body.
Answer :
 Muscular tissue.

Question. Define the term 'tissue’
Answer : Group of cells that are similar in structure and are organized together to achieve a particular function is called tissue.

Question. What are the functions of the stomata?
Answer : Stomata are essential for gas exchange with the atmosphere and help in transpiration in the form of water vapour through leaves.

 

Short Answer Type Questions

Question. Mention the types of simple and complex tissues.
Answer : Simple : (i) Sclerenchyma, (ii) Parenchyma, (iii) Collenchyma Complex : (i) Phloem (ii) Xylem

Question. Explain complex tissue in plants.
Answer : Generally, complex tissues consist of more than one type of cell. They are different in structure but together perform the same function.
There are two types of complex tissues :
1. Xylem : It transports water from roots to shoot in plants. The movement is only in one direction that is, from roots to shoot. It provides mechanical support to the plant. It has mostly dead elements. Its elements are tracheids, xylem sclerenchyma, xylem parenchyma, vessel elements.

2. Phloem : Conduct foods to all parts of the plant. The movement of phloem is bidirectional that is, movement in both the directions is possible. Its elements are mostly living. Its elements are sieve tubes, phloem parenchyma, companion cells and intermediary cells. Above given both complex tissues are conductive tissues and form the vascular bundle.

Question. Give one function of each of the following :
(a) Stomata, (b) Root nodules, (c) Cardiac muscle fibres. 

Answer : (a) Exchange of gases in plants.
(b) Root nodules are found in leguminous plants. They harbour bacteria which can fix free atmospheric nitrogen into nitrates and nitrites which plants like pulses can use for protein synthesis.
(c) Cardiac muscles show rhythmic contraction and relaxation throughout life. Because of this heart can pump the blood.

Question. What is the main function of vascular tissue in plants?
Answer : Vascular tissue transport :
(i) Water and dissolved minerals from roots to various parts of the plant (xylem).
(ii) Prepare food material from leaves to different plant parts (phloem).

Question. Give the types of meristematic tissues.
Answer : (i) Intercalary tissue — nodes (ii) Apical tissue — tips of shoot and roots (iii) Lateral tissue — stem sides


Question. Name the types of simple tissues.
Answer :
 The three main types of simple tissues are:
1. Parenchyma
2. Collenchyma
3. Sclerenchyma

Question. Give three features of cardiac muscles:
Answer : 
Below are features of cardiac muscles:
1. These are involuntary, show rhythmic contraction and relaxation throughout life.
2. The cells are cylindrical, branched, and uninucleate having faint cross striations.
3. These muscles do not get fatigued under normal conditions.

Question. How are simple tissues different from complex tissues in plants?
Answer :

Simple Tissue
Made up of only one type of cells.
Mainly responsible for mechanical support and storage.
Examples : Parenchyma, collenchyma and sclerenchyma
Complex Tissue
Made up of more than one type of cells.
Mainly responsible for the transport of water, minerals, sugars and other metabolites.
Examples Xylem and phloem.
