An introductory system to chemical phenomena

Atlay's Plant Physiology System is designed to introduce students to the basic phenomena that regulate plant life. The plastic cushioned box contains a complete set of glassware and laboratory items for investigating plant physiology. The experiments described in the Manual will lead students through the various phases of a plant's life from germination to photosynthesis and transpiration. The physical principles which regulate a plant's development, such as capillarity and osmosis, are explained first and then observed in living plants.
