66 Lessons9 hours4 weeks


Your body has many kinds of cells, each specialized for a specific purpose. Just as a home is made from a variety of building materials, the human body is constructed from many cell types. For example, epithelial cells protect the surface of the body and cover the organs and body cavities within. Bone cells help to support and protect the body. Cells of the immune system fight invading bacteria and so on. 

In this tutorial, we will introduce the cell. We will explore topics such as cell structure, structure and function of plasma membranes and cell metabolism. We started our study of Biology in the Biology 101 tutorial. It is recommended that you complete that tutorial before starting this tutorial.
