1: Cell Theory | By: Mariuna David Bilen Berhane IB Biolody HL
2: He stated that all living things are composed of cells and cell products. This contributed to the cell theory. | Theodor Schwann 1837
3: He invented the term "metabolism," and discovered yeast.
4: Robert Hooke 1660
5: His book, Micrographia, described his microscopic observations. He was one of the first persons to use the term "cell."
6: Ancient Egyptians 1500 B.C.
7: The priests who mummified learned a great deal about the human anatomy as they removed the vital organs from pharoahs. They were prevented to dissect due to their religion.
8: Lorenz Oken 1802 | He came up with a new system of animal classification, that included ..
9: Dermatozoa | Glossozoa | Rhinozoa | Otozoa | Ophthalmozoa
10: Medieval Europeans 1400 A.C.
11: Empiricism- knowledge arising gathered by sensory perception rather than rationalism | During the Renaissance, the discovery of many organisms were made and there was a renewed interest in empiricism.
12: Andreas Vesalius 1550 | He revolutionized medicine and corrected textbooks.
13: He assembled the first human skeleton from cadavers and was a poineer of human dissection. His work discredited long held beliefs about human anatomy contributed by Galen over 1000 years earlier.
14: Aristotle 384 B.C.
15: He dissected numerous organisms and liked to classify animals in order to establish a connection between the human body and the soul. Some animal classifications are credited today.
16: Louis Pasteur 1862 | He discovered vaccines for rabies and anthrax.
17: He came up with the idea of pasteurization which is based of his work in the germ theory. | He replaced the idea of spontaneous generation with biogenesis. | Biogenesis states all living things come from preexisting life.
18: He is considered the father of microbiology. He made his own microscopes and was the first to observe and describe bacteria and protozoa.
19: Anton van Leewenhoek 1674 | His research on invertebrates refuted the doctrine of spontaneous generation.
20: Rudolph Virchow 1850 | He accepted that the origins of cells was based on the division of preexisting cells.
21: He is known for his contribution to the cell theory that was built on the work of Theodor Schwann. | He was the first to discover leukemia cells.
22: Matthias Schleiden 1838
23: Great Grandparents | Parents | He stated that the different parts of plant organisms are composed of cells. | He recognized the importance of the cell nucleus.
24: Lazzaro Spallanzani 1768
25: Great Grandparents | His work suggested that all cells come from preexisting cells. | He stated that microbes could move through the air and cause spontaneous generation.
26: He noticed that the nucleus is present in every cell.
27: He was the first to recognize that the nucleus is an important part of living cells. | Robert Brown 1830
28: Francesco Redi 1668 | He discovered that rotting meat cannot make flies but only flies can make more flies.
29: His experiment on rotting meat disproved the theory of spontaneous generaation.
30: Jean Baptiste Lamarck 1800 | He is known for contributing to the theory of evolution. His primary contribution was the theory of inheritance.
31: He was able to create the first truly coherent theory of evolution.
32: John Needham 1750 | He believed that life occurs spontaneously at the microscopic level and therefore there is no need for reproduction.
33: However, his theory was disproved
34: Lorenz Oken 1802 | This includes invertebrates, mammals, reptiles, fish, and birds.
35: He came up with a new system of animal classification that shows the path of evolution.
36: Zacharias invented the first compound microscope that magnified nine times. However, this is debatable. | Hans, the father of Zacharias may have helped him with his inventions. Nevertheless, there is no proof.
37: Hans and Zacharias Janssen 1610 | Zacharias contributed advancements towards the invention of the telescope. However, some believe that he was the original inventor.
