Plant Physiology Experiments Under the Jar
For transpiration, wrap the pot and soil of a watered plant in polythene and cover the plant with the jar; water vapour given off by the leaves condenses as droplets on the inside of the glass. To show that photosynthesis needs carbon dioxide, keep a destarched plant under the jar beside a dish of potassium hydroxide, which absorbs the gas: its leaves then give a negative starch test with iodine, while a control plant without the absorber turns blue-black. A little grease on the rim seals the jar to its glass plate.
Bell jars of this shape are also used to hold a vacuum in other lab work. The glass is thin, so lift and set the jar down with both hands.
