BIO LAB 5

  1. Lenses to look through to view the specimen
    OCULAR LENSES
  2. Upper part of the microscope containing oculars and rotating nose piece
    HEAD
  3. Narrow, vertical part connecting the head and base. It may be straight or curved and supports the upper parts and provides a carrying handle
    ARM
  4. Revolving device located below the ocular lenses. It serves as an attachment for the objective lenses. The viewer can rotate the nose piece to change from one objective lens to another
    Rotating Nose Piece
  5. Magnification 4x The shortest of the objective lenses, used to scan the whole slide.
    Scanning Lens
  6. Magnification 10x. Longer than the scanning lens and is used to view objects in greater detail.
    Low power lens
  7. Magnification 40x. Used to view an object at even greater detail.
    High Power Lens
  8. Magnification 100x. Used in conjunction with immersion oil to view objects with the greatest magnification.
    Oil Immersion Lens
  9. Keeps the specimen slide stationary while viewing.
    Stage clip
  10. Two knobs that allow the movement of the specimen slide on the stage while viewing
    Mechanical Stage
  11. The flat platform connected to the arm and beneath the objective lenses, upon which the specimen slide is placed
    Stage
  12. A lens located just below the stage that concentrates light on the specimen. Best position is close to the stage.
    Condenser
  13. Knob allowing the viewer to control the position of the condenser
    Condenser Control
  14. A lever located beneath the condenser, regulates light passing through the condenser
    Iris Diaphragm Lever
  15. 2 knobs on either side of the microscope at the base of the arm. Usually the largest knobs on the arm. Turning them will raise and lower the stage
    Coarse adjustment knob
  16. 2 knobs usually located in the center of each coarse adjustment knob. Used for precision focusing. Raise and lower the stage in very small increments
    Fine adjustment knob
  17. A light within the base providing the light source for illumination of the specimen.
    Substage Light
  18. Dial that adjusts the light intensity allowed through the condenser on to the specimen
    Rheostat
  19. The supportive flat surface of the microscope that rests on the table
    Base
  20. All the organelles plus the cytoplasm
    Cytosole
  21. Similarities of Prokaryote and Eukaryotic Cells
    THERE ARE 4
    • 1. DNA
    • 2. CELL MEMBRANE
    • 3. RIBOSOME
    • 4. CYTOPLASM
  22. DIFFERENCES BETWEEN PROKARYOTE AND EUKARYOTIC CELLS
    THERE ARE 4
    • 1. MEMBRANE BOUND ORGANELLES
    • 2. SIZE
    • 3. NUCLEUS/ EUKARYOTE
    • 4. NUCLEOID/ PROKARYOTE
  23. 3 DOMAINS
    • 1. BACTERIA¬†
    • 2. ARCHAEA
    • 3. EUKARYA
  24. 6 KINGDOMS
    • 1. BACTERIA
    • 2. ARCHAEA
    • 3. FUNGI
    • 4. PLANTAE
    • 5. ANIMALIA
    • 6. PROTISTA
  25. LOVE EXTREME CONDITIONS
    EXTREMOPHILES
  26. Once an object is in focus using the scanning lens; it will remain in coarse focus when the lenses are changed to higher power. DON'T HAVE TO REFOCUS
    PARFOCAL
  27. What you see when you look through the microscope.
    FIELD OF VIEW
  28. Occular X Objective
    Total Magnification
