Final answer:
Robert Hooke is generally credited with the discovery of cells.
Step-by-step explanation:
The discovery of cells is generally credited to Robert Hooke. In 1665, Hooke coined the term 'cell' after observing box-like structures in cork tissue through a microscope. Although Anton van Leeuwenhoek made important discoveries using his own microscope, including observing human cells and bacteria, Hooke is generally credited with the discovery of cells.
