Science Level 5
Unit 3 Cells to Body Systems
The walls of your house are made up of bricks. Have you ever thought about what is your body made up of? All living things are made up of tiny cells. These cells can not be seen with naked eye. If you want to see plant cells and animal cells, you need a microscope.
In this unit you will learn a lot about cells, the functions of the cells, the human body systems, and how these systems work all together.
