  1. Epithelial tissue is a protective tissue. [T]
  2. Muscular tissue show the property of contraction and expansion. [T]
  3. Cyton and axon are the parts of a nerve cell. [T]
  4. The fluid part of the blood is called plasma. [T]

VI. Answer the following questions :

Question 1 :- Define the term ’tissue’.

Answer: A group of similar cells that work together to do the same job is called a tissue .

Question 2 :- Name the  different types of animal tissues.

Answers: The different types of animal tissues are :

(a)Epithelial tissue

(b)Connective tissue

(c)Nervous tissue

(d)Muscular tissue

Question 3 :- Describe the structure and function of following tissues:

Epithelial tissue, Muscular Tissue, Nervous Tissue, Connective tissue.

Answers:- The structure and function of the following tissues are :-

(a) Epithelial tissue : Epithelial tissue is a protective tissue. It forms a continuous outer layer all over the body as a part of the skin. It also forms a lining of all organs such as the stomach, oesophagus (food pipe), mouth, intestine, and trachea (windpipe).

  • Structure: The structure of the cell may be flattened, cuboidal or columnar.
  • Functions: Protection, Absorption, and Secretion

(b) Muscular Tissue: The movement of body or its parts in most animals is brought about by a group of cells which show the property of contraction and relaxation. These cells are called muscular cells.

  • Structure: Cardiac, smooth, and skeletal are the structures of muscular tissue.
  • Function: Muscular tissues  helps our body in movement, posture, joint stability, and heat production.

(c) Nervous Tissue : Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities.

  • Structure: Nervous tissue is made up of different types of nerve cells, all of which have an axon. An axon is the long stem-like part of the cell that sends action potential signals to the next cell.
  • Function: It is responsible for coordinating and controlling many body activities.

(d) Connective tissue: Connective tissue are the type of tissues that binds and supports other tissues of the body. The types of connective tissue include cartilage, bone, tendon, adipose tissue .

  • Structure: It is made up of a few cells present in the intercellular framework of protein fibres secreted by the cells.
  • Function: It connects different tissues of the body and provides shape and support to it. It also reserves food material in the form of fat.

Question 4 :- How is connective tissue different from other tissues?

Answer:  The connective tissue serves the purpose of connecting different parts of the body. They are different from other tissues as their cells are separated from each other and are embedded in ground substance or matrix.

The composition of this gel-like substance will vary according to the type of tissue-like solid in case of bone or liquid in case of blood or semi-solid in case of connective tissue proper

Question 5 :- Draw the structure of a nerve cell.

Answer: The structure of a nerve cell.

Lining of stomach, Wall heart, Blood, Brain

Answers: The tissue found in the following are:-

(a) Lining of stomach: Columnar epithelium

(b) Wall heart: The cardiac muscle tissue

(c) Blood: Fluid Connective tissues

(d) Brain: Nervous tissue
