First Compound Microscope
Made by Hans Janssen and his son Zacharias. Is A tube with lens at each end. Telescopes envetion gave the ability for people to notice cells. -
Hooke's Compound Microscope
Stand on the right holds oil for flame, and shines light on the specimen under the microscope -
Leeuwenhoek's Simple Microscope
Used only one tiny lens adn can magnify up to 266 times. Was the first Microscope to see Bacteria. -
Caspar Wolf
Discoverd all organs in animals embroyos are made of globules which could be seen in microscopes. -
Henri Dutrochet
Staeted all organic tissues are globular cells united by adhesives forces. -
The Cell Theroy
All living things are composed of cells. Cells are the basic unit of structure and function in living things. All cells are produced from other cells. -
Schleiden and Schwann
Made a discovery of livings things but not cells.Thought living things came from non living matter. -
Virchow
Discoverd that new cells only come from existing cells. -
Modern Compound Light Microscope
The horeshoe satnd keeps Microscope steady. The mirror focuses light up through the specimen.Can Magnify up to 1,000 times. -
Trasmission Electron Microscope (TEM)
A German Physicist created this Microscope. Makes images by sending electrons through thinly sliced speciamen. Can magnify up to 500,000 times. -
Scanning Electron Microscope
Sends a beam over the surface of a specimen. the results are tree dimensional. Can magnify up to 150,000 times. -
Scanning Tunneling Microscope
Electronic that tunnels from surface of specimen. Scientists can see individual molecules of outer layer on cells. Can magnify up to 1,000,000 times. -
Genes
Humans are thought to have 30,000 to 40,000. Can be as short as 1000 base pair in DNA sequences.
