Discovery of Cells & Cell Theory PowerPoint covers the history of the discovery of cells. The powerpoint begins with Hooke and his cork cell observations and leads up the conversation of Schwann and Schleiden. Their work led to the foundation of the modern cell theory.
The power point goes on to give a brief overview of prokaryotes and eukaryotes and how cellular differentiation is the driving force behind the evolution of prokaryotes into eukaryotes and single cellular organisms into multicellular organisms.
This is an excellent quick introductory lesson to the cells and the history of their discovery.
