This file is regarding - Chapter 3 of the book, An Alien Hand, of English, Grade 7, NCERT. It contains Picture board, that helps the reader to understand the chapter quickly and in an interesting way through comics. It contains solutions of the questions given in the textbook. It contains the key points of the chapter and also some quick links to make the chapter more interesting videos and quizzes.
This module will help you gain knowledge about cell: the basic unit of all living matter. It is the unit of structure and function of which all plants and animals are composed. The cell is the smallest unit in the living organism that is capable of integrating the essential life processes. The cell is the key to biology because it is at this level that life truly springs. As you read this, you will learn more about the activities of the cell, the structures and the material of life that fills them. Later on, you will discover what a living matter is made of.
