Tissues| Worksheet Solutions| Class 9

Worksheet solutions for chapter: Tissues for class 9 are provided below.

(1) Identify plant tissues and animal tissues among the given examples-

Meristematic tissue, epithelial tissue, simple permanent tissue, muscular tissue

Ans-

Plant tissues and animal tissues are tabulated below –

SN Examples Plant Tissue Animal Tissue
1. Meristematic tissue Yes No
2. Epithelial tissue No Yes
3. Simple permanent tissue Yes No
4. Muscular tissue No Yes

 

(2) What is differentiation in permanent tissues?

Ans- The process in which permanent tissues cells are taking up permanent shape, size is called differentiation. Differentiation leads to the development of various types of permanent tissues.

 

(3) Differentiate between xylem and phloem.

Ans- Differences between xylem and phloem are tabulated below –

SN Xylem Phloem
1. It consists of tracheids, vessels, xylem parenchyma and xylem fibres.

 

It consists of five types of cells which are sieve cells, sieve tubes, companion cells, phloem fibres and the phloem parenchyma.
2. Many of Tracheids and vessels are dead cells when mature. Except phloem fibres, other phloem cells are living cells.
3. It transports food from roots to stems and leaves. It transports food from leaves to other part of the plant.

 

(4) What is cuboidal epithelial tissue?

Ans- The epithelial tissues which are found in lining of kidney tubules and ducts of salivary glands where it provides mechanical support are known as cuboidal epithelial tissues. Cuboidal epithelial cells are cube shaped epithelial cells.

 

(5) What are nerve impulse and its importance for our body?

Ans- The signal that passes along the nerve fibre is called a nerve impulse. It is very important for our body because it allows us to move our muscles when we want to.

 

(6)Differentiate between ligament and tendon?

Ans- Differences between ligament and tendon are tabulated below –

SN Ligament Tendon
1. It is very elastic. It is less flexible.
2. It connects bone to bone. It connects bone with muscles.

 

(7) Write similarities and dissimilarities of involuntary and voluntary muscles.

Similarities of involuntary and voluntary muscles

SN Voluntary Muscle Involuntary Muscle
1. Muscular tissue Muscular tissue
2. Found in animal tissue Found in animal tissue

Dissimilarities of involuntary and voluntary muscles

SN Voluntary Muscle Involuntary Muscle
1. Muscles move according to us. Muscles do not move according to us.
2. It is also known as striated muscle. It is also known as unstriated muscle.
3. The cells of voluntary muscle tissue are long, cylindrical, unbranched and multinucleate.

 

The unstrained muscles cells or involuntary muscles cells are long with pointed ends (Spindle – shaped) and uninucleate.

 

4. Eg:- Muscles present in limbs move when we want to move and stop when we want to stop.

 

Eg:- Iris of eye, in ureters and in the bronchi of lungs.

 

 

(8) What is function of cuboidal epithelial tissue?

Ans-  The cuboidal epithelial tissues are found in lining of kidney tubules and ducts of salivary glands. These tissues provide mechanical support to the body.

 

(9)Draw one type of epithelial tissue?

Ans- The columnar epithelial tissue is diagrammatically presented below –

(10) Identify the type of tissue in examples given below:

Hair like projection in respiratory tract, tissues present in limbs, tissue in ureters, spinal cord tissues

Ans- Identification of tissues are tabulated below –

SN Examples Type of tissue
1. Hair like projection in respiratory tract ciliated columnar epithelium
2. Tissue present in limbs Voluntary muscle
3. Tissues in ureters Involuntary muscle
4. Spinal cord tissue Nervous tissue
