  17. MICROSCOPES • The earliest simple microscope was merely a tube with a plate for the object at one end and, at the other, a lens which gave a magnification less than ten diameters -- ten times the actual size. These excited general wonder when used to view fleas or tiny creeping things and so were dubbed "flea glasses."

  18. About 1590, two Dutch spectacle makers, Zaccharias Janssen and his son Hans, while experimenting with several lenses in a tube, discovered that nearby objects appeared greatly enlarged. That was the forerunner of the compound microscope and of the telescope. In 1609, Galileo, father of modern physics and astronomy, heard of these early experiments, worked out the principles of lenses, and made a much better instrument with a focusing device.

  19. Robert Hooke, the English father of microscopy, re-confirmed Anton van Leeuwenhoek's discoveries of the existence of tiny living organisms in a drop of water. Hooke made a copy of Leeuwenhoek's light microscope and then improved upon his design.

  20. OpticalMicroscope • An optical microscope, also called "light microscope", is a type of a compound microscope that uses a combination of lenses magnifying the images of small objects. Optical microscopes are the oldest type and simplest to use and manufacture.

  21. Digital Microscope • A digital microscope has a digital CCD camera attached to it and connected to a LCD or a computer monitor. A digital microscope usually has no eyepieces to view the objects directly. The trinocular type of digital microscopes have the possibility of mounting the camera, that would be an USB microscope.

  22. FluorescenceMicroscope • A fluorescence microscope or "epifluorescent microscope" is a special type of a light microscope, instead of light reflection and absorption used fluorescence and phosphorescencea to view the samples and their properties.

  23. ElectronMicroscope • An electron microscope is one of the most advanced and important types of microscopes with the highest magnifying capacity. In electron microscopes electrons are used to illuminate the tiniest particles. Electron microscope is a much more powerful tool in comparison to commonly used light microscopes.

  25. AnswerKey

  26. Protists are a DiverseGroupofAnimals

  27. MOST OF THEM ARE UNICELLULAR

  28. BUT THERE ARE MULTICELLULAR TOO... • Multicellular protistshavesimplerstructuresthananimals, plantsorfungi; • Theyalsohavefewertypesofcells (sometimesonly 1).

  29. Protists Come in a VarietyofShapesandSizes Euglena Diatoms Seaweed

  30. Protistsobtainenergy in threeways: • Photosynthesis (Plant-likeprotists); • Parasitism (Animal-likeprotists); • Decomposition (Fungus-likeprotists).

  31. Plant-likeprotists: ALGAE • There are unicellularand multicellular algae.

  32. Animal-likeprotists: PROTOZOA Paramecium

  33. Fungus-likeprotists: MOLDS
