1 Lab: Cells

2 What will we be looking at under a microscope in this lab?  Bacteria Cells  Plant Cells  Animal Cells

3 Specimen Whatever you want to look at under a microscope. (e.g. hair, blood, cells, insects, etc.)

4 Preparing Microscope Slides: 1. Grab a clean glass slide. 2. Place specimen on middle of slide. 3. Put one drop Iodine (Blue Dye) on top of specimen. 4. Cover specimen with a cover slip. Specimen Iodine

5 Cover Slip Purpose of a cover slip is to cover the specimen and iodine so that the objective lens does not get wet. Specimen + Iodine

6 Microscope: Eye Piece Lens = 10 x Low Power Objective = 4x High Power Objective = 10x

7 What will you be viewing? CellsSpecimen AnimalHuman Cheek Cells PlantElodea BacteriaStrep (Causes Strep Throat)

8 Cheek Cells – Low Power

9 Cheek Cells – High Power

10 Purpose of Iodine: Outlines the big parts of the cell such as the Nucleus and Plasma membrane.

11 Elodea Cell – Low Power

12 Elodea Cell – High Power Label nucleus and chloroplasts on drawing!

13 Bacteria – High Power
