Answers
Answer:
Robert Hooke:- Robert Hooke coined the term as cell. When he was observing a piece of cork under a primitive microscope he saw some small boxes where as monks lived and named it as a cell.
Leeuwenhoek:-Antony van Leeuwenhoek is regarded as the father of microbiology. He is known for the discovery of bacteria.Leeuwenhoek discovered "protozoa" - the single-celled organisms and he called them "animalcules". He also improved the microscope
Robert Brown:-Although Scottish botanist Robert Brown (1773-1858) was responsible for discovering the nucleus of a cell, he is perhaps best known for hisdiscovery of the random movement of microscopic particles in a surrounding solution, later referred to as "Brownian motion."
Explanation:
Robert Hooke (1635-1703) is an English physicist. He contributed to the discovery of cells while looking at a thin slice of cork. He then thought that cells only exist in plants and fungi. In 1665, he published Micrographia.
As well as being the father of microbiology, van Leeuwenhoek laid the foundations of plant anatomy and became an expert on animal reproduction. He discovered blood cells and microscopic nematodes, and studied the structure of wood and crystals. He also made over 500 microscopes to view specific objects.
His discovery of the nucleus and its role helped to prove the cell theory, which states that all living organisms are composed of cells and cells come from pre-existing cells. Other discoveries and contributions of Brown include: The discovery and naming of over 2000 species of plants.
