CELL THEORY SCIENTISTS
Modern Cell Theory Robert Hooke
Modern Cell Theory contains 4 statements, in addition observed cells in cork
to the original Cell Theory: coined the term “cells”
The cell contains hereditary information described cells as “tiny holes” or
(DNA) which is passed on from cell to cell “honeycomb”
during cell division thought cells existed only in plants and fungi
All cells are basically the same gin chemical
composition and metabolic activities Anton van Leuwenhoek
All basic chemical & physiological functions used a handmade microscope to observe pond
are carried out inside the cells (movement, scum & discovered single-cell organisms
digestion, etc.) called them “animalcules”
Cell activity depends on the activities of sub- observed blood cells from fish, birds, frogs,
cellular structures within the cell ( organelles, dogs, and humans
nucleus, plasma, membrane) it was known then that cells are found in
animals as well as plants
The 3 Basic Components of the Cell Theory were Robert Brown
now complete: noticed pollen grains in water jiggled
All organisms are composed of one or more called “Brownian Motion”
cells (Schleiden & Schwann) discovered Nucleus
The cell is the basic unit of life in all living discovered nuclei within the cells, pave the
things (Schleiden & Schwann) way to discover other nuclear components,
All cells are produced by the division of pre- chromosomes & DNA
existing cells (Virchow 1858)
Felix Dujardin
How Has The Cell Theory Been Used? described a formless substance, sarcode –
The basic discovered truths about cells, listed in the protoplasm
Cell Theory, are the basics for things such as:
Disease/Health/Medical Research and Curses (AIDS, Matthias Schleiden
Cancer, Vaccines, Cloning, Stem Cell Research, etc.)
botanist
concluded that “all plants are made of cells”
Theodor Schwann
zoologist
concluded that “all animals are made of cells”
Rudolph Virchow
physician
did research on cancer cells
concluded “Omnis cellula e cellula” / “All
cells are from other pre-existing cells”
cells must arise from pre-existing cells
