Cheek Cell Lab
AFTER you have completed the rest of this lab come back to this cover page
DRAW & LABEL A CHEEK CELL WITH ALL THE PARTS / ORGANELLES YOU OBSERVE UNDER 40X.
Purpose: To observe and identify major animal cell structures and to relate the structure
of the cell to its function.
Materials:
toothpick
iodine stain
slide & cover slip
your cheek cell(s)
Procedure:
1. Use the blunt end of the toothpick to (gently) rub the back inside of your cheek
2. Put a drop of iodine stain on the slide & smear the end of the toothpick around in the
drop to release the cells
3. Carefully place a coverslip to avoid air bubbles
4. Observe your slide under 4X power - draw what you see - identify & label cell parts -
write a brief description of your observations & magnification next to each drawing.
5. Observe your slide under 10X power - draw what you see - identify & label cell parts -
write a brief description of your observations & magnification next to each drawing.
6. Observe your slide under 40X power - draw what you see - identify & label cell parts -
write a brief description of your observations & magnification next to each drawing.
