THE CELL The Cell Theory. Types of cells. Parts of a cell. Fernando Gómez A cell by * quick2004

All things on earth can be classified into 2 groups. Can you group these items into these 2 main groups? LIVING or NON LIVING Record your answers in your journal.

All things on earth are either living or non-living .

All living things are made of one basic unit. Can you name it?

In your journal, write a paragraph about how living things are different from non-living things. Be sure to include information about the basic unit of life.

The Vital Functions : When speaking about the difference between living and non-living things we have to appeal to the vital functions , that is: Nutrition Interaction and Reproduction.

Cells are the basic unit of life . This is a single cell of a living thing.

Definition of Cell A cell is the smallest unit that is capable of performing life functions.
