Oxygen was the substance produced by the mint plant. Joseph Priestley enclosed a mint plant in a container, along with a burning candle. After the flame consumed all the oxygen, it went out. Despite the fact that the mint plant was in a closed container, after another 27 days had passed, Priestley was able to reignite the candle. This proved that plants produce oxygen, which is a gas that allows fuels to burn.
In 1772, Priestley made another important discovery. He had placed a shoot of a green plant into a container of water. He then covered the container and lit a candle in it until it completely burned out. Later, Priestley was able to both burn the candle again and keep mice alive in the air (did they have lab mice back then?). Priestley became the first person ever to observe the photosynthesis in plants - the fact that they take in carbon dioxide and release oxygen.

In the conduct of the experiment, two steps are tested.One setup is called the experimental setup.
J. Arditti has written: 'Experimental plant physiology'
In general, heat waves do not have any effect on the biomass of a plant in an experiment. The heated water or water from a microwave also does not affect the plant.
