Animal Tissues — Overview

Animal tissues are groups of specialised animal cells that perform functions such as protection, support, movement, and coordination.

In one line: Cover, connect, contract, conduct: the four animal tissue jobs.

Practice This Concept

Understand it

The four main animal tissues are epithelial, connective, muscular, and nervous tissue. Epithelial tissue covers and protects, connective tissue joins and supports, muscular tissue helps movement, and nervous tissue carries messages.

Example

Skin has epithelial tissue for protection, blood is a connective tissue for transport, and nerves carry impulses.

Rule to remember

Classification rule: epithelial covers, connective supports or transports, muscular contracts, nervous conducts impulses.

See it worked out

Follow the example line by line, then use the same method on new questions.

Worked example

When you touch a hot object, nervous tissue carries the message, muscles pull the hand away, and connective tissues support movement.

Method you can reuse

Find the action described in the question, match it with protection, support, movement, or coordination, then name the tissue type.

Visual tip

A four-branch chart can show epithelial, connective, muscular, and nervous tissues with one example under each branch.

Check yourself

Answer the question in your head before opening the answer.

Try it yourself

Why is blood considered a connective tissue?

Think first, then show answer

Blood is considered a connective tissue because it connects different body parts by transporting gases, nutrients, wastes, and other materials through the body.

Common wrong answer

Calling blood an epithelial tissue.

Why it loses marks: Blood transports materials and has a fluid matrix, so it belongs to connective tissue.

Don't mix this up

Students often think blood is not a tissue because it is fluid, but it is a connective tissue.

Exam tip

For one-mark answers, name all four animal tissues; for longer answers, add one function and one example each.

Write it in the exam

Each point is worth about one mark. Write point 1 for a 1-mark question and keep adding points as the marks go up.

How CBSE asks it

Questions may ask to classify a tissue from its function, such as contraction, protection, transport, or impulse conduction.
