Cell Theory Anton Von Leeuwenhoek

Created 1st light microscope

Robert Hooke Coined the term “cells” –

resembled little rooms in monastery

Cell Theory Matthias Schleiden

Stated that all plants are made of cells Theodor Schwann

Stated that all animals are made of cells

Cell Theory

Robert Brown Discovers nucleus’(dark

center)role in division Rudolf Virchow

See & describe cell division

Cell Theory

1. All living things are made of cells.

2. Cells are the basic unit of structure & function.

3. All cells come from pre-existing cells.

Prokaryotic Cells Simplest cell No nucleus or organelles Contains cell wall/membrane,

cytoplasm, ribosomes, genetic material

Ex: bacteria

Eukaryotic Cells True Cells – those containing a nucleus Ex: Plant & animal cells
