Lab-Aids: Differentiation of Cells Experiment Kit Cell Differentiation is a process by which development of a living organism is achieved. Through a series of progressive changes, a generalized cell transforms into a specialized cell. The more specialized the cell becomes; the less likely it is to divide. After the seeds germinate, students prepare slides, then watch living material differentiate before their eyes. They will also observe generalized cellular divisions in meristematic root cap tissue and isolate specialized cells. In the final activity, students diagram and label the differentiated cells. This experiment can also be used for independent student investigation. MICROSCOPES ARE NEEDED. Scientific Concepts: Observe differentiation of cells Prepare slides use microscopes Isolate specialized cells Observe generalized cellular divisions in root tip tissue Content List: 1 Teacher's Guide with MSDS 50 Student Worksheets and Guides 12 LAB-AIDS‚® Chemplates‚® with spatulas and gas collector caps 12 Gas delivery tubes 1 Absorbent paper, pkg 1 Vial of Calcium carbonate chips 1 Vial of Unknown #1 1 Vial of Unknown #2 1 Vial of Unknown #3 1 Vial of Unknown #4 1 Drop controlled bottles of Barium chloride solution 1 Drop controlled bottles of Antimony chloride solution 1 Drop controlled bottles of Cadmium nitrate solution 1 Drop controlled bottles of Lead acetate solution 1 Drop controlled bottles of Potassium permanganate solution 1 Drop controlled bottles of Sodium sulfate solution 1 Drop controlled bottles of Sodium sulfite solution 1 Drop controlled bottles of Zinc nitrate solution 3 Drop controlled bottles of 6M Hydrochloric acid 3 Drop controlled bottles of Limewater, saturated 3 Drop controlled bottles of Sodium sulfite solution Classroom Planning: To complete this kit requires one ~50-minute class period.
