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.
What does the name of this chapter tell us?
Image: A simple comparison showing a single brick next to a full brick house, beside a single cell next to a whole human body, to show cells are the building blocks of life.
  • 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
