Problem:



Hypothesis: If I use a light microscope, then I will see
                             in a plant cell and
                                                           in an animal cell.

Materials:
*                                      *
*                                      *
*                                      *

*                                      *

Procedures:
   1. Make a ____________ or ___________cell wet slide:
         Part 1: Making a __________ cell slide
         - Get a clean ___________ & cover slip
         - Place 1 ____________ leaf onto the slide.
         - Add __________drops of water onto the specimen
         - Cover with a_________ _________. Avoid air bubbles.
         - Wipe or soak up any excess liquid from the slide.
         Part 2: Making an _____________ cell wet slide
         - Get a clean slide &_____________ ___________ .
         - Add ______ drops of methylene blue dye to the slide.
         - Gently rub the inside of your ____________ with the flat end of
         the_______________. (Do NOT gouge yourself!)
         - Swirl the toothpick __________ the methylene blue solution.
         - Cover with a cover slip. Avoid _________ bubbles.
         - Wipe or soak up any excess liquid from the slide.
   2. Place the cell slide under the microscope and focus on _______
      power (4x) using __________ fine and coarse adjustment knobs to
      focus.
   3. Draw what you see then label all the cell______________.
4. Move the slide around so that a clump of cells is at the __________
   of your microscope slide. Look into the microscope as you are doing
   this.
5. Switch from low objective lens to ___________objective lens (10x).
   Focus using both the fine & coarse adjustment knob.
6. _____________ what you see then label all the cell organelles.
7. Switch from medium objective lens to high objective lens (______x).
   Focus using ONLY the ____________(smaller) adjustment knob.
8. Draw what you see then label the cell organelles.
9. Now do steps 2-8 for the other cell slide.
10. Clean slides and cover slips, return the equipment and clean up your
desk area.

  Analysis:

1. What were the similarities that you observed between plant and animal

  cells?




2. What were differences you saw between plant & animal cells?




3. Why did we have to add dye to the animal cells but not the plant cells?

  What organelle gave the plant cells their color?
