FAQs on Tissues Class 9 Science Chapter 6 Biology Part 1 CBSE NCERT KVS

Question 1

1. What are tissues?

Accepted Answer

Ans. Tissues are groups of similar cells that work together to perform a specific function in an organism. They are the building blocks of organs and are classified into four types: epithelial, connective, muscular, and nervous tissues.

Question 2

2. What is the function of epithelial tissue?

Accepted Answer

Ans. Epithelial tissue covers the body surfaces, lines the internal organs, and forms glands. It acts as a protective barrier, regulates the exchange of materials between the body and the external environment, and helps in the absorption and secretion of substances.

Question 3

3. How is connective tissue different from other types of tissues?

Accepted Answer

Ans. Connective tissue is different from other types of tissues as it is characterized by having a matrix or ground substance that separates and supports the cells. It provides structural support, connects different tissues and organs, stores fat, and transports nutrients and waste materials.

Question 4

4. What are the types of muscular tissues?

Accepted Answer

Ans. There are three types of muscular tissues: skeletal, cardiac, and smooth muscles. Skeletal muscles are attached to bones and help in voluntary movements. Cardiac muscles form the walls of the heart and are responsible for involuntary contractions. Smooth muscles are found in the walls of organs and blood vessels, controlling their movements.

Question 5

5. How does nervous tissue function?

Accepted Answer

Ans. Nervous tissue is responsible for transmitting and receiving electrical signals in the body. It consists of specialized cells called neurons that communicate with each other and with other body parts. Nervous tissue helps in coordinating and controlling body functions, such as sensory perception, motor control, and memory.
