Question 1. What is tissue ?


Tissues are the group of cells which are similar in structure and perform a specific function.

Question 2.What is the utility of tissue in a multicellular organism? 


A multicellular organism consists of numerous cell. To perform a specific work a group of similar cells has to work together. Therefore some similar type of cells combined together to format issue and perform respective functions.

Question 1. Name the types of simple tissue. 


The different types of simple tissues are 


Question 2. Where is the apical meristem found?


ethical meristems I found in the apical region tips of plants this tissue helps in growth of the plant in upward direction.

Question 3. Which tissue makes up the husk of coconut ? 


The husk of coconut is composed of sclerenchyma tissue. This tissue is made up of dead cells which makes it very hard.

Question 4. What are the constituents of phloem?


The phloem tissue is made up of four types of cells. They are -

Sieve tubes  
Companion cells 
Phloem fibre
Phloem parenchyma.

Question 1. Name the tissue responsible for movement in our body. 


The tissue which is responsible for movement in our body is muscular tissue. 

Question 2. What does a neurone look like?


A neurone (nerve cell) looks like a thread  having some branches around the main cell body. These branches are known as dendrites. The longest branch extending from the cell body is called axon which ends in some nerve endings. A neurone is the longest cell found in our body.

Question 3. Give three features of cardiac muscles.


Our heart is composed of a special type of muscles called cardiac muscles. Some features of these muscles are as follows - 
  • The cells are cylindrical in shape. 
  • They are branched having a single nucleus. 
  • Some faint bands are present. 

Question 4. What are the functions of areolar tissue? 


Areolar tissue is found between the skin and the muscles, around the blood vessels, nerves and in the bone marrow. It fills the space inside the organs, supports and helps in repairing of tissue.

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


 Xylem tissue is made up of four types of cell. They are - 

  •   Tracheits 
  •  Vessels 
  •  Xylem Parenchyma
  •  Xylem Fibre 

Question 3. How is simple tissue different from complex tissue? 


 The differences between simple tissue and complex tissue are are are as follows - 

  •  Simple tissue is consist of only one type of cells whereas complex tissue is made up of a different type of cells.

  •  In simple tissue, all the cells perform some functions but in complex tissue different cells perform different functions. 

  • Simple tissue is of three types whereas complex tissue is of two types.

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


Parenchyma - The cell walls are relativity thin and made up of cellulose. 

Collenchyma - In Collenchyma cell walls are irregularly thick at the corners and there is very little space between the cells. 

Sclerenchyma - The cell walls are uniformly thick. There is no intermolecular space between the cells. An additional layer of cell wall composed of lignin is found. 

Question 5. What are the functions of stomata? 


The function of stomata are as follows - 
It allows the exchange of changes ( Co² and O²) with the atmosphere. Evaporation of water also takes place through it. This process is called transpiration.

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


The specific function of cardiac muscle is to contract and relax continuously throughout the life of an organism. It is an involuntary muscle.

Question 8. Differences between striated, unstrained and cardiac muscles on the basis of their structure and site/location.


                        Striated muscles 

Structure -  Cells are cylindrical. They are not branched coma alternate light and dark bands are present.  Cells are multinucleid. 

Location -  These muscles are present in hands, legs, tongue etc. 

         Unstriated muscle 

Structure - cells are spindle-shaped and uninucleated. No alternate bends are present. These are involuntary muscles.

Location - these muscles are present in the alimentary canal and in the blood vessels. 

Cardiac Muscles

Structure -  cells are cylindrical and branched. They are uninucleate and some faint bands are present. 

Location -  Present in the heart. 

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


Skin- Epithelium Tissue 
The bark of a  tree - Collenchyma
Bone- Connective Tissue
The lining of kidney tubule- Cuboidal Epithelial Tissue
Vascular bundle- Complex Permanent Tissue 

Question 12. Name the regions in which parenchyma tissue is present answer tissue is found in the leaves coma fruits and flowers. 

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


 The epidermis is present in the outer surface of the entire plant body. The cells of this tissue form a  continuous layer without any intercellular space between them. It performs the following functions- 

  • It is a protective tissue of the plant body.
  • It protects the plant from external injuries.
  • It allows gases exchange in the environment.

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


The outer protective layer or the outer bark of a tree is known as cork. It is made up of dead cells. Therefore it is hard and it protects the plant against injuries, change in temperature etc. It also prevents the loss of water by evaporation. 

Question 15. Complete the table.

Question 2. What are the different types of meristematic tissue? 


 Depending on the region where the meristematic tissues are present , they are classified as apical, lateral and intercalary. 

Question 3. What is apical meristem?


 Apical meristem is present at the growing tips of stems and roots and increases the length of the stem and the root.

Question 4. What is lateral meristem? 


The growth of the stem or root increases due to lateral meristem (cambium).

Question 5. What is intercalary meristem? 


Intercalary meristem is the medicine at the base of the leaves or internodes (on either side of the node) on twigs.
