Question

What was Robert Hooke’s contribution to biology?

Answer 1

Hint: For his work in the sciences, such as astronomy, physics, and biology, Robert Hooke is recognized as a "Renaissance Man" 17th century England. Robert Hooke was an Oxford-educated scientist who worked for the Royal Society and Gresham College. His investigations and studies included astronomy, biology, and physics; he is most known for the findings he made with a microscope and "Hooke's Law" of elasticity. In 1703, Hooke died in London.

Complete answer:
Hooke’s contribution to biology can be summarized as follows:
Hooke devised and built a compound microscope with a novel screw-operated focusing mechanism. Previously, getting the specimen in focus necessitated moving it. With the addition of illumination, he was able to further enhance the microscope. He used a water-lens next to the microscope to concentrate light from an oil lamp on his specimens, which was vividly illuminated.
Hooke examined the microscopic structure of the bark of a cork tree. As a result, he found and called the cell, which is the basic unit of life. He thought the things he had uncovered resembled the separate chambers known as cells in a monastery. The real biological role of cells was not discovered by Hooke. He observed honeycomb-like cork cells.
In 1665, Hooke found the first known microorganisms, which were tiny fungus. This was nine years before Antonie van Leeuwenhoek discovered single-celled life.

Note:
Micrographia by Sir Robert Hooke was a collection of complex drawings that depicted the first major set of observations made with an early microscope fitted with compound magnifying lenses (his finely-detailed drawing of a flea is famous). Insects, sponges, bryozoans, diatoms, and bird feathers were among the creatures Hooke saw. In his groundbreaking discovery of plant cells with cell walls, Hooke created the term "cell" in a biological sense, describing the microscopic structure of cork as a little barren chamber or monk's cell.
