saw cells in pond water, which he called "animalcules"
proposed that all plants are made of cells
proposed that all animals are made of cells
proposed that all cells come from preexisting cells
Which are the different parts of the cell theory?
Every living thing is made of one or more cells.
All cells come from ribosomes.
The cell is the basic unit of structure and function in an organism.
All cells come from preexisting cells.
Why is the cell theory a theory and not a fact?
Because people didn't want others to add or take away from the theory.
Because some people aren't sure it is thoroughly investigated.
Because new discoveries could arise and disprove the theory.
Because new discoveries could prove it even more.
