Study Notes
Cell Theory Pioneers
- Robert Hooke: English scientist who first used the term "cell" to describe cells, discovered this while examining cork in 1660.
- Anton van Leeuwenhoek: Dutch scientist, major contributor to microscopy, built over 500 microscopes in his lifetime. Observed single-celled organisms ("animalcules") but failed to observe how they reproduced.
- Robert Brown: Scottish physician, in the 1830s, first used the term nucleus.
- Mathias Schleiden: Noted that cells are the fundamental units of plants.
- Theodore Schwann: Compared animal cells to plant cells.
- Rudolf Virchow: Stated that all cells come from pre-existing cells, challenging the theory of spontaneous generation, and described cell formation from the inside out.
Cell Theory
- Cells: fundamental unit of all life.
- All living organisms composed of one or more cells.
- Cells are the smallest unit exhibiting the characteristics of life.
- Cells originate from pre-existing cells.
