Here are the four parts of the cell theory: 1) All living things are made of cells. 2) Cells are alike in structure and function. 3) Cells need information in order to survive. 4) New cells come from old cells. Why are cells so small? The cell theory never states ...

However, from their research, it was Lorenz Oken (born in 1779 and died in 1851) who wrote one of the main facets of cell theory: that cells and other microscopic elements were the foundation of life.
cleus, but his ideas of a community of cell type structures have been lauded in many quarters as a pioneering effort in cell theory.7 When the first fertilized mammalian ovum was identified and described by Carl Ernst von Baer in 1828, he acknowledged Oken's early contribution and singled out Generation as a seminal work in the field.
