Robert Hooke
Robert Hook discovered a honeycomb-like structure in a cork slice by looking at it in a primitive compound microscope. He was actually looking at the remnant of cells that made the cork and the cells looked like rooms that monks lived in at monasteries and these rooms in latin are known as " cellula" which is where the word "cell" originates from. Because of his observation, that gave Hooke credit for the discovery of the building block of all life. -
Anton van Leeuwenhoek
Leeuwenhoek is the first to observe and describe bacteria that was located on his teeth, but he didn't call it a bacteria. He called it "animacules". He was able to make these observations with the microscopes that he made which consist of a high-quality len of very short focal length. HIs microscopes contained a magnification power of 270x. -
Henri Dutrochet
Henri Dutrochet is a French physiologist who discovered and the phenomenon of osmosis and was the first to recognize the importance of the green pigment in the use of carbon dioxide by plant cells. -
Félix Dujardin
Dujardin proposed that there are many living organisms that consist of a single cell. He also observed the presence of the internal substance of all living cells and found they were similar. -
Theodor Schwann
Theodor Schwann is a German physiologist that stated that all animals are composed of similar structures. With the help of Schleiden's discovers, they both help come up part of the cell theory that states that all living organisms are made up with cells. -
Matthias Schleiden
Discovered that no matter the plant, they all had similar structures that make up the plant. Those structures that made up those plants were also similar to those of the cork that Hooke discovered. -
Rudolf Virchow
Rudolf Virchow is a German physician that was using a microscope and observed that at the right time, bacteria divided and formed two bacteria and was identical when it came to their apperance. He stated in Latin "ominis cellula e cellula" and when translated it means every cell originates from other cells like it which another part of the cell theory.
