Study Notes
The Cell
- A cell is the smallest unit of a living thing
- Cells are the basic units of structure and function in living organisms
- A living thing, whether single-celled or multi-celled, is called an organism
- Cells are the basic building blocks of all organisms
The Cell Theory
- Cells are too small to be seen without a microscope
- In 1665, Robert Hooke used a microscope to observe cork cells, and named the compartments “cells”
- Hooke observed small compartments in dead oak cells (cork)
- After Hooke, many improvements were made to microscopes and techniques to study the details of cells
- This led to the development of cytology (the study of cells)
- Improvements allowed biologists to study the internal structure of cells in different organisms
- In 1838, Mathias Schleiden and Theodor Schwann stated that plants and animals are composed of identical cells
- In 1859, Rudolf Virchow stated that cells come from pre-existing cells
- The statements of Schleiden, Schwann, and Virchow form the basis for the development of cell theory
