Several scientists helped develop the cell theory! :)
I discovered the cellular composition of cork and invented the term¨cell¨. This helped develop the idea that cells make up everything.
The nucleus in plant cells were discovered by me.
Matthias Jakob Schleiden
I discovered that all plants were made up of cells.
I proposed the theory that all plant and animal tissues are composed of cells and all the cells are identical.
I discovered that all living cells come from other cells.In conclusion, these scientists including myself helped develop the three parts of the cell theory.The three parts are that all living things are made up of cells,cells come from pre-existing cells,and the cell is the unit of structure for all living organisms including plants and animals.
