All living things — both plant and animal — are made of tiny blocks called cells. Each cell is a tiny factory with a special job to do. Some help us move, some carry messages, some protect, and some build strength.

Here is the amazing story of how a cell is born, what it is made of and how it works with trillions of other cells to make us what we are.

This lucid and comprehensive discussion of cells is designed to answer the young reader's questions and to give him an elementary understanding of the cell as the basic unit of life.
