The ____stereoscopic______ microscope is used to view items that are too large or too think. 4. The ___revolving nosepiece____ supports the various objectives (4x, 10x, 40x). 5. The _____stage_______ supports the specimen being observed. 6. The __coarse focus knob____ permits rapid change in distance between the specimen and the objective. 7. The ___fine focus knob___ permits small changes in distance between the specimen and the objective. 8. The _______________________ is the piece with which one looks at the specimen. 9. The _______________________ is the magnifying element that is closest to the specimen. 10. The _______________________ is a system of lenses that concentrates the light furnished by the illuminator. 11. The _______________________ allows one to focus the concentrated light onto the specimen. 12. The _______________________ is used to reduce glare from unwanted light by adjusting the _______________________ of the cone of light that comes from the condenser. 13. The 40x on the objective engraving represents the __magnification___. 14. The 0.95 located on the right of the 40x represents the __numerical aperture / resolving power of the objective____. 15. The 160 / 0.17 below the above represents the __maximum coverslip thickness (mm)___. 16. If the ocular or objective is dirty, you use _kimwipes_ to wipe them. 17.

The __reflected__ light is directed unto ___opaque____ specimens whereas the _____transmitted____ light is directed unto ______translucent_______ specimens. 24. Cells can be organized into two types: _____eukaryotic_____ and __prokaryotic__ cells. 25. ___Eukaryotic___ cells are much larger than _prokaryotic___ cells. 26. Linear chromosomes are seen in ___eukaryotic____ cells, while circular chromosomes are seen in ___prokaryotic____ cells. 27. The eukaryotic specimen used in this lab is named ___elodea___ and it is a ___plant____ (plant or animal?) 28. __photosynthesis__ takes place in the chloroplasts of the Elodea leaf. 29. ___chlorophyll_____ is responsible for the green colour of the Elodea. 30. ___cytoplasmic streaming____ is the directed flow of the cytosol and organelles around plant cells. 31. The __plasma membrane__ cannot be seen in plant cells under the microscope because it is too thin. To resolve this problem, ___5% NaCl___ is added to the specimen, which removes the __cell wall__ from the plant, making the plasma membrane more visible. The organism that has the cell minus the cell wall is called a ___protoplast____.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
