Q:- Who discovered the first cell?
-> Robert Hooke...
Robert Hooke discovered the cell in England in 1665.He took microscopy as a hobby and used to view various specimen under his microscope. Once he was looking at a cork through a microscope and found small boxes he called cells.Since corks are made from the oak trees, they were made up of cells. He named it a cell because it reminded him of a monks cell in a monastery.That ís how the cell was discovered.
Robert Hooke was born in 1635 in Freshwater on the Isle of Wight to John Hooke and Cecily Gyles. As a youth, Robert Hooke was fascinated by observation, mechanical works, and drawing, interests. In 1665 Hooke published Micrographia, a book describing his microscopic and telescopic obs
ervations, and some original work in biology.Apart from his work in biology Hooke is principally known for his law in elasticity ie; Hooke's law.

Hooke was an important architect of his time, and a chief surveyor to the City of London after the Great Fire. He built some of the earliest Gregorian telescopes, observed the rotations of Mars and Jupiter, and, based on his observations of fossils, was an early proponent of biological evolution.

He investigated the phenomenon of refraction, deducing the wave theory of light, and was the first to suggest that matter expands when heated and that air is made of small particles separated by relatively large distances. He also deduced from experiments that gravity follows an inverse square law, and that such a relation governs the motions of the planets, an idea which was subsequently developed by Newton. Much of Hooke's work was conducted in his capacity as curator of experiments of the Royal Society, a post he held from 1662.
