The cell theory, or cell doctrine, states that all organisms are composed of similar units of organization, called cells. Hans and Zacharias Jansen invent their own design of the microscope (compound microscope) that could only be used for opaque objects and has a magnification of 20x. 1650. By creating the microscope that allowed Robert Hooke to discover the first cells, Jansenn gave him the tool he needed to make an innovative discovery, II. Created by. Germany: 1879 : Scientific development : Using the microscope, German biologist Walter Flemming discovers cell mitosis and chromosomes, a scientifc achievement recognized as one of the most importants of all time. Therefore, the purpose of amicroscope is to magnify the object, making the image large enough to get abetter view. Students will: describe and/or explain the cell theory. Learn.

The First Microscope In 1590 dutch lens maker Zacharias Jansenn built the first microscope which viewed objects about 20 to 30 times bigger. Although this knowledge is foundational today, scientists did not always know about cells. Cell Theory and Discovery of the Microscope 1.

In this time in WW1 the Germans had used mustard gas as chemical warfare but then at the University of Yale had found that if you inject it into the blood stream that the substance rapidly made white blood cells, so in doing so they had came up with a idea that if they injected this into people with cancer the white blood cells whould kill off the cancer cells. – Life arose as nuclei formed cells. 2) All existing cells are produced by other living cells. He saw cell walls and said they looked like tiny rectangular rooms. Cell Theory. The original cell theory states that the cell is the basic structural and functional unit of living organisms and all cells come from other cells. There had been many diffrent types of cameras in history but i will be focusing on the one that Robert Boyle had made.

VIrchow discovered that all cells come from cells that already exist. zThis is reductionism. 1839. These observations led two German scientists, named Theodor Schwann and Matthias Jakob Schleiden, to propose that cells are the basic building blocks of all living things. And that is when chemotherapy was born. He suggested that all cell come from pre-existing cells. A timeline created with Timetoast's interactive timeline maker.
