Description (TISSUE – Lecture 1 | Class 9 CBSE)

In this lecture, we begin a new chapter of Class 9 Biology titled “Tissue”.
A tissue is defined as a group of similar cells that work together to perform a specific function.

Both plants and animals are made up of different types of tissues. Each tissue has a unique structure and function, which helps the organism survive and work efficiently. Understanding this chapter is very important because it forms the foundation of Biology for higher classes.

In this lecture, you will learn:

What is a tissue?

How tissues are formed from cells

Why tissues are necessary in multicellular organisms

Basic introduction to plant tissues and animal tissues


This lecture is completely CBSE-oriented and explained in simple and clear language for Class 9 students.
