e. none of the above

Answer 1

d. All of the above.

Please note:

In 1665, Robert Hooke first used the word cell to name the microscopic honeycomb cavities in cork. His studies of microscopic fossils led him to become one of the first proponents of a theory of evolution.

In 1674, Anton van Leeuwenhoek made an important contribution to the development of cell theory. He was the first to observe bacteria and protozoa and believed that there were seeds or eggs too small to see by the eye being planted into food, and other things.

In 1838, Matthias Jakob Schleiden and Theodor Schwann discovered that all plants are made of cells. This was a major breakthrough in the field of biology, as it was the first time that it was shown that all living things are made of cells.
