In this chapter we will learn about cells and how they are studied under a microscope, the cell membrane and the cell wall, the interior of the cell and its many organelles, how cells grow and divide, and the cell theory that ties all living things together.
Understanding the Name of the Chapter
Cell
The smallest living unit in the body of any organism.
Building
Putting many small parts together to make something bigger.
Block
A basic piece used again and again, like a brick.
Life
Everything that is living, from bacteria to a giant tree.
- The cell is the brick from which all living bodies are built.
- Single cells or millions of cells together make every living thing.

Are living things made of one cell or many?
Living things
One cell or many?
1. Unicellular
Made of one cell
Example:
Bacteria, yeast
2. Multicellular
Made of many cells
Example:
Plants, animals, humans
- A cell is the basic unit of life.
- Just like bricks build a house, cells build a body.
-
Some living things are of one cell. Example - Bacteria, yeast
And some living things are made up of millions of cells. Example - Plants, animals, humans
