Cells and the Cell Theory Section 1 The Diversity of Cells Cells and the Cell Theory Finding Cells in Other Organisms In 1673, Anton van Leeuwenhoek, a Dutch merchant, made his own microscopes. Leeuwenhoek was the first person to see bacteria. And he discovered that yeasts that make bread dough rise are single-celled organisms. The Cell Theory All organisms are made of one or more cells. The cell is the basic unit of all living things. All cells come from existing cells.

The Diversity of Cells Cell Size Section 1 A Few Large Cells Most cells are small. A few, however, are big. A chicken egg is one big cell. Many Small Cells There is a physical reason why most cells are so small. Cells take in food and get rid of wastes through their outer surface. As a cell gets larger, it needs more food and produces more waste. Therefore, more materials pass through its outer surface. As the cell’s volume increases, its surface area grows too. Learn how to calculate a cells surface area-to-volume ratio in the next slide.
