Cellular Structures Microscopy Study
Directions: Make a wet mount slide of Onion epidermis, Elodea leaf, Human cheek cells, teased lichen,
paramecium, and filamentous algae as demonstrated by your instructor. Make a careful drawing of what
you see and label each drawing with the expected labels for each type of cell.
Making a Scientific Drawing:
1) Drawings must be in PENCIL
2) Drawings must be neat. If it is not you will lose points. Science is about accuracy, not your best effort.
3) Drawings must be labeled. This includes the magnification that was used to view the sample.
4) Label lines should be horizontal when possible and labeled with a letter. The letter should be defined
in a key under the title of the sample. The edges of the lines should meet at the same edge.
Example:
Palmate Leaf:
Key: a = midrib, b = blade, c = petiole, d = stipule
