Purpose To identify the difference between plant and animal cells, recognize their structures, and to better understand the various functions of those cell organelles.

II. Background In 1665 Robert Hooke used an early light microscope to look at a thin slice of cork. Under the microscope the cork looked to have thousands on empty chambers, which Hooke noted looked like “cells”, so he coined the term.
Anton van Leeuwenhoek was a Dutch scientist who was named the father of microbiology. He was the first person to look at living cells and bacteria under a slightly more advanced single-lens microscope in 1676 and 1683.
Matthias Schleiden was a German scientist who observed different plants in the late 1830’s. His observations concluded that the plants were all composed of cells. Another German scientist, Theodor Schwann, observed that animals were also composed of cells.
Later on, Rudolf Virchow concluded that the nucleus was the structures responsible for cell division, which created the third part of the cell theory, stating that all cells came from other pre-existing cells.

The Cell Theory is as follows -
1. All organisms are composed of one or more cells
2. The cell is the basic unit of structure in organisms
3. All cells come from pre-existing cells
