Cells are known as building blocks or basic structural unit of life.

As the blocks can be joined in many ways to make the building of different shapes and sizes. In the same way all living organisms are made differently of Different shapes, sizes and by different number of cells.

The Cell were discovered by Robert Hooke, English scientist in 1665 with his home made crude microscope he examined a thin slice of Cork and observed that it had comb like structure. He called these thick walled room like structure Cells.

In 1674 with improved microscope, Anton von leeuwenhoek discovered small components within the cell.

Some living organisms are made up of single cell. These are called Unincellular Organisms. The Organisms like Amoeba, paramoecium and Bacteria are the examples of Unincellular Organisms. Most of the organisms are made of many cells called Multicellular Organisms like Mushrooms, human being, Animals etc.

There are millions of living organisms. They are of different shapes and sizes. Their organs also vary in shape, size and number of cells.

Cells → Tissues → Organs → Organ System → Organism.
