Robert Hooke
Hooke discoverd the first cell or pores when he first saw them. He was looking at cork and the cells first appear to him as pores but later changed it to cells. He also made microscopes that move up and down for scienist later on. -

Leeumenhoek
In 1674, He was first to see and describe bacteria, yeast plant drop of water, and the circulation of blood corpuscles in capillaries. He made the most advanced microcscopes that led to the discovery of the bacteria. He could go into 270x magifaction which was better than hooke's microscope but which might have also help Leeuwenhoek discovery. -
Dujardin
He was the first to group single-cell animals and named them as "Rhizopoda", which is now called as protozoans.Dujardin's studies of flatworms laid foundation for the future work of parasitologists.Later in 1835 Dujardin based on his studies of organisms under a microscope proposed that many living organisms are composed of a single cell and also observed the presence of internal substance. Dujardin disproved Ehrenberg's theory which states that "tiny animals have the same organs as large ones". -
Dutrochet
In 1837, he is investgated the osmosis, respiration, embryology and the lights of plants. He looked at plants that have osmosis and respiration pattern through microscope. His model disproved becasue he went into more cells of the plants cells in a spefic type of plant and discoverey the osmois cell in plant. -
Schwann
Schwann observed animal cells under the microscope, noting their different properties. He was very into muscles cells inside the body. He looked into a microscope and discoverd cells inside the body. His models was better becasue he looked more into a bunch of living cells not just on area of cells and different cells that was in the same liveing organism. -
Virchow
In 1845, Virchow and John Bennett independently observed abnormal increase in white blood cells in patients. Virchow correctly identified the condition as blood disease. Another significant credit relates to the discovery, made approximately simultaneously by Virchow, that an enlarged left supraclavicular node is one of the earliest signs of gastrointestinal malignancy, commonly of the stomach, or less commonly, lung cancer. His model was better because he discoverd many types of cancer cells. -
Schleiden
He concluded that all plant parts are made of cells and that an embryonic plant organism arises from the one cell. Schleiden preferred to study plant structure under the microscope. His model was disproved Schwann models becasue not only does body cells have mutiple areas but also that plants have more to. -
