Petroleum jelly, also known as soft white paraffin, has numerous uses in biology practicals including being used as a way of investigating stomatal function and transpiration. One great example is the ever popular potometer practical where vaseline is used to seal round the plant stem to ensure an air-tight seal.

SAPS also give details for an Investigation into Leaf Surface Temperature which uses petroleum jelly to block plant stomata.
