Period 1-4
Purpose: Identify and label cell parts in diagrams of plant and animal cells.
List each cell part’s function
Describe characteristics that distinguish plant cells from animal cells
Materials:
 1 Microscope
 1 Elodea leaf
 Onion skin
 Cheek cells
 1 Microscope slide
 1 Cover slip
 1 Prepared Amoeba slide
 Water and eye dropper
 Iodine
 Safety Goggles
Procedure:
1. Make a wet mount slide of elodea. Find a layer of large cells on high power. Identify the parts and answer
questions located in the lab guide.
2. Prepare a wet mount slide of the onion skin. Stain it with iodine. Examine cells under low, medium and high
power. Draw and label 3 onion cells on high power (put them all on the same page) and answer the questions.
3. Make a wet mount slide of your cheek cells. Scrape the inside of your cheek with a toothpick and add a drop of
iodine before adding the cover slip. On high power draw and label three cheek cells and answer the questions.
4. Obtain a prepared amoeba slide. On high power draw and label 2 amoeba cells and answer the questions.
5. Complete the questions at the end of the lab guide and draw a generalized plant and animal cell.
