Tissues
TEXTUAL QUESTIONS AND ANSWERS
Textbook Page No. 69
1. What is a tissues.
Answer:- A tissue is a group of cells that are similar in structure and are organized together to perform a specific task. Tissues are of four types: muscle, epithelial, connective and nervous. Each is made up of specialized cells which are grouped together according to structure and function.
2. What is the utility of tissues in multicellular organisms?
Answer:- The utility of tissues in multicellular organisms is to provide defined structure, mechanical strength, and division of labor. This division of labor makes multicellular organisms able to perform all functions efficiently.
Textbook Page No. 74
1. Name types of simple tissues.
Answer:- The different types of simple tissues are mentioned below:
(i) Parenchyma.
(ii) Collenchyma.
(iii) Sclerenchyma.
2. Where is apical meristem found?
Answer:- Apical meristem is present at the growing tips of stems and roots. Its main function is to trigger the growth of new cells in young seedlings at the tips of roots and shoots and forming buds.
3. Which tissue makes up the husk of coconut?
Answer:- The coconut husk is composed of sclerenchyma tissue.
4. What are the constituents of phloem?
Answer:- The constituents of phloem are sieve tubes, companion cells, phloem parenchyma and phloem fibres.
Textbook Page No. 78
1. Name the tissue responsible for movement in our body.
Answer:- Muscular tissue is responsible for movement in our body.
2. What does a neuron look like?
Answer: A useful analogy is to think of a neuron as a tree. A neuron has three main parts: dendrites, an axon, and a cell body or soma (see image below), which can be represented as the branches, roots and trunk of a tree, respectively.
3. Give three features of cardiac muscles.
Answer:-
Three features of cardiac muscles are:
(i) Cardiac muscles are involuntary muscles that contract rapidly, but do not get fatigued.
(ii) The cells of cardiac muscles are cylindrical, branched, and uninucleate.
(iii) They control the contraction and relaxation of the heart.
4. What are the functions of areolar tissue?
Answer:- The function of areoalr tissue are mention below:
(i) To function as supporting and packing tissue between organs, lying in the body cavity.
(ii) To bind bones to bones, muscles to bones, skin to muscles, etc.
(iii) To repair tissues after injury.
(iv) To help in combating foreign toxins.
(v) To fix skin to underlying muscles.
(vi) To help in diffusion of oxygen and nutrients from small blood vessels.
EXERCISES (Textbook Page No. 79)
1. Define the term “tissue”.
Answer:- A tissue is a group of cells that are similar in structure and are organized together to perform a specific task. Tissues are of four types: muscle, epithelial, connective and nervous. Each is made up of specialized cells which are grouped together according to structure and function.
2. How many types of elements together make up the xylem tissue? Name them.
Answer:- Xylem tissue is a complex tissue composed of four types of elements.
These elements are:
(i) Tracheids.
(ii) Vessels or tracheae.
(iii) Xylem parenchyma and.
3. How are simple tissues different from complex tissues in plants?
Answer:- Simple tissues different from complex tissues in plant are mentioned below:
|
Simple tissues |
Complex tissues |
|---|---|
|
These are made of same types of cells |
Thes are made up of different types of cells. |
|
Cell in simple tissues performs same function. |
Cells in complex tissues performs two or more functions. |
|---|
4. Differentiate between parenchyma, collenchyma and Sclerenchyma on the basis of their cell wall.
Answer:- The different between parenchyma, collenchyma and sclernchyma on the basis of their cell wall are mentioned below:
|
parenchyma |
collenchyma |
Sclerenchyma |
|---|---|---|
|
Cell wall is thin. |
Cell wall is think. |
Cell wall is hard rigid very thick |
|
Made uo of cellulose. |
Made uo of celluloses and pectin. |
Made up of lignin – a water proof mwterials. |
5. What are the functions of stomata?
Answer:- The main functions of stomata are mentioned below:
(i) Absorption of mineral salts: They help the plants to transpire and hence loss of excess water from plants occurs. This helps in absorption of mineral salts by root tissues.
(ii) Facilitates photosynthesis: They allow gaseous exchange between the atmosphere and internal environment of the plants, i.e. exchange of O₂ and CO₂. Thus, photosynthesis is not possible without them.
6. Diagrammatically show the difference between the three types of muscle fibres.
Answer:-
7. What is the specific function of the cardiac muscle?
Answer:- The specific function of cardiac muscle is rapid but rhythmic contraction and relaxation throughout life without fatigue. They contract endlessly from early embryonic stage until death. Such contraction helps to pump and distribute blood to various parts of the body.
8. Differentiate between striated, unstriated and cardiac muscles on the basis of their structure and site/location in the body.
Answer:- The different between striated and cardiac muscles on the basis of their structure and site/ location in the body are mentioned below:
|
Striated muscles |
Unstriated muscles |
cardiac muscles |
|---|---|---|
|
They are cylindrical in the shape and multi nucleate . |
They spindle shaped and uninucleate. |
They are cylindrical branched abd uninucleate. |
|
They present body parts such as hands and legs. |
They are present in the wall of food canal , stomach, mouth , iris etc. |
They present in the heart. |
9. Draw a labelled diagram of a neuro.
Answer:-
10. Name the following.
(a) Tissue that forms the inner lining of our mouth.
Answer:- Squamous epithelium.
(b) Tissue that connects muscle to bone in humAnswer:-
Answer:- Tendon.
(c) Tissue that transports food in plants.
Answer:- Phloem.
(d) Tissue that stores fat in our body.
Answer:- Adipose tissue.
(e) Connective tissue with a fluid matrix.
Answer:- Blood.
(f) Tissue present in the brain.
Answer:- Nervous tissue.
11. Identify the type of tissue in the following: skin, bark of tree, bone, lining of kidney tubule, vascular bundle.
Answer:- Skin: Squamous epithelium.
Bark of tree: Collenchyma-cork protective tissue.
Bone: Connective tissue.
Lining of kidney tubule: Cuboidal epithelium.
Vascular bundle: Conducting tissue-xylem and phloem.
12. Name the regions in which parenchyma tissue is present.
Answer:- The parenchyma tissue can be found in the leaf, fruits, as well as flowers. It can also be found in the petiole tissue, leaves, phloem, & vascular bundles.
13. What is the role of epidermis in plants?
Answer:-
Epidermis is a protective tissue of angiospermic plants. It provides protections to underlying tissues. Epidermis forms outer covering of various plant organs such as roots, stem, leaves, and flowers and remains in direct contact with the environment. Any substance whether solid, liquid or gas can enter into the plant or move outside only after passing through this layer. Epidermis helps in absorption, secretion, gaseous exchange and transpiration. It helps in preventing the entry of pathogens.
14. How does the cork act as a protective tissue?
Answer:- The cork cells are dead cells and do not have any intercellular spaces. The cell wall of the cork cells are coated with suberin (a waxy substance). Suberin makes these cells impermeable to water and gases. Cork is protective in function; it protects underlying tissues from desiccation, infection and mechanical injury.
