CELL MICROSCOPE INVESTIGATION • Objective: – To learn characteristics of all cells – To identify cell parts – To compare and contrast various cell types• Plant and animal cells – To develop microscope skills Elodea Plant - A water plant 40X Scanner 400X High Power Field Of View Diameter = 8 cells Of F.o.V. = 1.5 mm 100X Diameter = 2 cells = 0.375 mm 400X 1000X 1000X Parts of cell are--- “organelles” Nucleus Nucleolus SPIROGYRA - algae Tree leaf cross section Tomato Your turn! 1. Create a wet mount slide of onion skin – Stain w/ Lugol’s iodine – Examine – Draw and Label 2. Create a slide of cheek cells – Stain w/ methyl blue – Examine – Draw and Label Drawings must be neat, use colored pencils, accurate in size and scale 100X Cytoplasmic streaming or cylosis E. Coli bacteria cell Nerve cells = Neurons Amoeba proteus
