Q. 1. Who discovered cells, and how?
Cells were discovered in 1665 by Robert Hooke. He was examining a thin slice of cork using a primitive microscope designed by himself. He saw that the structure of the cork at a microscopic level is similar to that of a honeycomb. It had several small chambers like those in a honeycomb. These small chambers were termed cells.
As i know robert hooke invented cell in the late 1667s
