Lesson 1 The Cell

  Introduction

Did you know the fundamental unit of life is the cell?

This means everything that is alive or was once alive is made up of these tiny building blocks. In this unit, you will learn all about cells and their functions. You will learn what cells are made of and how they carry out the basic functions of life. You will also study different techniques for seeing very small objects and how these techniques have changed over the years. Finally, you will study plants as an example of a complex organism. By looking at how are grouped together into systems in plants, you will start to understand how animal systems work. This will help you get ready for Biology 20, should you decide to take that course.

  General Outcomes

By the end of this unit, you will be able to

1. explain the relationship between the developments in microscopes and the current understanding of the cell

2. describe the functions of cell structures in terms of life functions and use models to explain these functions
   

3. use plants as an example of a multicellular organism with structures designed for specific functions
