The below mentioned article includes a collection of ten experiments on photosynthesis for high school. 1. Experiment to demonstrate Moll's half-leaf experiment for showing that CO2, light, chlorophyll and water are necessary requirements for photosynthesis: Requirements: A potted plant, caustic potash, wide- mouthed bottle, iodine, split cork, water. Method: 1. De-starch a potted plant by putting it in complete darkness [...]
Object: To demonstrate the phenomenon of diffusion. Requirements: Beaker, water, copper sulphate crystals. Method: Take a clean beaker and fill it completely with water. Place a big crystal of copper sulphate on one side of the beaker (Fig. 1). Observations: After some time, crystal of copper sulphate disappears and its particles get equally distributed throughout the water. Results: Molecules of [...]
Object: To separate the chlorophyll pigments by Thin Layer Chromatography (T.L.C.). Requirements: Spinach leaves, slides, staining tube, acetone, benzene, mortar, pastel, Kieselgel G, drier, pencil, sand, distilled water and oven. Preparation of T.L.C. Slides: 1. Prepare a slurry of Kieselgel by suspending about 2 gm. of Kieselgel in 10 ml. of distilled water. 2. Take 4 clean microscopic slides and [...]
