### Introduction

(Under Construction. Links will be added.)

In this chapter we will be investigating the parts of a typical cell.

Check out the cell above. Like all cells it has three main areas: The cell membrane, the cytoplasm, and the nucleus. You can investigate any one of these areas. If you know nothing about the structure of the cell it would probably be smart to go through the pages in the order presented. (just like you would read your regular text book). If you are looking for a particular topic go to the index below and click directly on that topic.
