Q.

What is a tissue?

Answer    

Tissue is a group of related cells that have a common

origin and perform a common function.


 

Q.2What is the utility of tissues in multi-cellular

organisms?

Answer     

In multi-cellular organisms, the different types of tissues

performs different functions. Since a particular group of

cells called tissue perform  a particular function, they do

it very efficiently. 


Thus, multi-cellular organisms possess

a definite division of labour.tissues provide structural

strength, mechanical strength and division of labour.

Q.1 Name the tissue responsible for the movement in our body?

Answer     

Muscular tissues and nervous tissues. Combination of both tissues is responsible for the movement in our body.

 

Q.2 What does neuron look like?

Answer    

Neuron look like a miniature tree with thin hair like parts arising from its ends.   Neuron  has a cell body with a nucleus and cytoplasm. Each neuron has a single long part called axon. A neuron has many short hair like structure called dendrites.

 

Q.3 Give three features of cardiac muscles.

Answer     

(i)  The cells of cardiac muscles are cylindrical, branched and uninucleate.

(ii) These are involuntary and can’t controlled by us.

(iii)These muscles show rhythmic contraction and relaxation throughout the  life.

 

Q.4 What are the functions of areolar tissue?

Answer    

Areolar tissue support internal organs and helps in repair of the tissues.they are connective tissues fond in animals and present between skin and muscles, around blood vessels and nerve and in bone marrow. These tissues fill the space inside the organs.

Q.5 What are the functions of stomata?

Answer    

Functions of stomata:

(i)They are sites where exchange of gases occurs

between the plant interior and external environment.


(ii)     Major part of transpiration occurs through stomata.


(iii)They regulate both gaseous exchange and

transpiration.

 

Q.6 Diagrammatically show the difference between the three types of muscle fibres.

Answer    

Muscle fibres are of three types-

b. They are connected to bones.

c. They are voluntary muscles.

striated muscle


 (ii). Smooth muscles

a.  They are involuntary muscles.

b.  They are found in alimentary canal and lungs.

c. They are spindle shape and have single nucleus.

   

Smooth muscles

(iii). Cardiac muscles 

a.They are found in heart.

b.They are involuntary muscles.

c. They are cylindrical, branched, and uni-nucleate.
      

Cardiac muscles

                                                

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

Answer     

Cardiac muscle contracts and relaxes rapidly and

continuously with a rhythm. Their rhythmic contraction

and relaxation helps in pumping of blood.

muscles on the basis of their structure and site/location in

the body.

Answer     

 

         

Differentiate between striated, un-striated and cardiac  muscles

  (a) Tissue that forms inner lining of our mouth

  (b)  Tissue that connects muscle to bone in humans.

  (c)  Tissue that transports food in plants.

  (d)  Tissue that stores fat in our body.

  (e)  Connective tissue with a fluid matrix.

  (f)   Tissue present in the brain.

Answer    

(a)  Stratified squamous epithelium.

(b)      Tendon

(c)       Phloem

(d)      Adipose tissue

(e)      blood  

(f)        Nervous tissue

 

Q.11 Identify the type of tissue in the following: skin

bark of tree, bone, lining of kidney tubule, vascular

bundle. 

Answer

     

Skin: Epithelial tissue.

Bark of tree: Cork (Protective tissue)

Bone: connective tissue

Lining of kidney tubule: Cuboidal epithelium tissue

Vascular bundle: Complex or conducting tissue (xylem

and phloem)


 

Q.12Name the region in which parenchyma tissue is

present.

Answer 

Parenchyma is found in almost all non-woody parts of

the plant such as-cortex, pith, medullary rays of stem,

cortex and pith of roots, leaf flowers, pith of fruits etc. it

is a basic packing tissue.

 

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