What did Jan van Helmont discover?
Jan Baptista van Helmont (1580-1644) partially discovered the process of photosynthesis. He grew a willow tree in a weighed amount of soil. After five years, he discovered that the willow tree weighed about 74 kg more than it did at the start.

How did Van Helmont discover carbon dioxide?
Credit for the discovery of carbon dioxide goes to Flemish scientist Jan Baptista van Helmont (c. 1580–1644; some sources give death date as 1635). Around 1630, van Helmont identified a gas given off by burning wood and gave it the name gas sylvestre (“wood gas”). Today we know that gas is carbon dioxide.
What was Van Helmont experiment?
Jan Van Helmont wanted to prove plants use materials from the soil to perform photosynthesis. So he performed an experiment where he took a pot of soil and a willow seedling and weighed the pot of soil and the willow tree separately. Then he planted the willow tree by sunlight and watered it every day.

Where did Jan Ingenhousz discover photosynthesis?
Ingenhousz placed submerged plants in sunlight and then in the shade. He noticed that small bubbles were produced by the plants when they were in the sunlight. When they were transferred to the shade bubbles were no longer produced by these plants. Ingenhousz later concluded that plants use light to produce oxygen.
What did Jan Ingenhousz discover?
Dutch-born British physician and scientist Jan Ingenhousz is best known for the discovery of the process of photosynthesis, by which green plants in sunlight absorb carbon dioxide and release oxygen.

How did van Helmont test the theory of growth?
The prevailing theory at the time was that plants grew by eating soil, and van Helmont devised a clever investigation to test this idea. He weighed a willow tree and weighed dry soil. He planted the tree, watered it and then left it for 5 years. He then re-weighed the tree, which had increased in mass by over 12 stone.
