Study Notes
Cell Structure and Functions
- Living things, like non-living things, are made from chemical elements like carbon, hydrogen, oxygen, and nitrogen
- Cells are the fundamental building blocks of living matter
- Cells are the smallest unit of life that can carry out all life processes
- Cells are composed of molecules
Discovery of the Cell
- In 1665, Robert Hooke, an English scientist, used a crude microscope to examine a cork tree section. He observed tiny chambers and named them "cells."
- Anton van Leeuwenhoek, a Dutch scientist, improved the microscope and observed other cells in 1670.
- Matthias Schleiden (German botanist) and Theodor Schwann (German physiologist) in 1838 proposed that all plants and animals are made of cells.
- Rudolf Virchow (German researcher) in 1858 formalized the cell theory
Cell Theory
- The cell is the basic structural and functional unit of life
- All organisms are composed of cells
