In this experiment Ingenhousz demonstrated that plants are dependent on light and their green parts for nutrients and energy.
For more photosynthesis experiments look here:
Repeat Joseph Priestley's Experiments:
took Priestleys work further and demonstrated that it was light that plants needed to make oxygen (oxygen was discovered a few years earlier, in 1772 by ).
However, Jan Ingenhousz was the first person to show that light is essential to the plant process that somehow purifies air fouled by candles or animals.
We exhale the carbon dioxide that plants need for photosynthesis.
Many scientists contributed to the discovery and understanding of photosynthesis throughout the ages; in this page are outlined some of those crucial milestone experiments that contributed to this effort.
Jan Baptista van Helmont, Flemish physician, chemist, and physicist, in the 1600s carried out a famous experiment by growing a willow tree in a pot for five years.
