With the invention of the microscope it helped Robert Hooke discover cells. He observed the thin slices of a cork using a microscope and found out something that looks like compartment rooms which he then called cells
Robert Hooke: Fascinating! so this is how the cork looks under a microscope, since it looks like room cells I'll call it cells
Matthias Schleiden: Plants are composed of cells
Many years after Hooke's discovery on cells both Schleiden and Schwann co-founded the cell theory which Made the 1st and 2nd Postulate of Cell theory " All living organisms are composed of cells and Cells are the basic units of structure and function on organisms"
Theodore Schwann: All animals are composed of cells
Rudolph Virchow is at his work when he noticed that the cells he is observing keeps dividing
Rudolph Virchow: hmm... the cells are dividing to form other cells but I'm still skeptical if all cells do this.
When Rudolph Virchow found out about the work of robert remark, he was sure that every cell comes from other cells. He has proven the 3rd Postulate of Cell theory " All cells come from preexisting cells through the process of cell division."
Yes! cells really do come from other pre-exiting cells
