The microscope was the invention that made it possible for scientists to discover and learn about cells. Its ability to magnify small objects allowed scientists to observe cells for the first time, leading to the development of the cell theory in the 19th century.
The discovery of the cell was possible due to the invention of the microscope.
One invention was the cell phone.
The cell phone was not discovered, it was invented. The man who invented the cell phone was Martin Cooper, who worked as an engineer at Motorola.
Matthias Shleiden discovered that plant tissues are composed of cells and that an embryonic plant arose from a single cell. He declared that the cell is the basic building block of all plant matter.

Since he obviously helped with the improvement of the microscope, his higher lens quality helped him see a single cell organism. Well, if a single cell organism exists, spontaneous generation is corrupt. He really just proved what Zacharias Jensen did.
The microscope was the invention that allowed us to discover cells. In the 17th century, with the improvement of microscope technology, scientists were able to observe and characterize cells for the first time.
Because if they didnt come up with a telephone invention we wouldn't have cell phones.
