Biology Name: ______________________________ Per: ______ Date: _____________________ 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 b a c d Onion Epidermis: Use Lugol’s Reagent as a stain Labels: Cell wall, Starch granules KEY: Magnification: _________ Elodea Leaf: Labels: Cell Wall, Central Vacuole, Chloroplast KEY: Magnification: ___________ Human Cheek Cell: Use Methylene Blue as a stain Labels: Cell Membrane, Nucleus KEY: Magnification: ___________ Lichen: Labels: Fungal Mycorrhizae, Algae cell KEY: Magnification: ___________
