Who discovered photosynthesis?

Answer 1

Jan Baptista van Helmont, a Flemish chemist, physiologist, and physician, discovered the beginnings of photosynthesis.

He performed a biological experiment on a willow tree in 1643. He carefully measured the mass of the soil used by a plant and the mass of the plant as it grew. After noticing that the soil mass changed very little, he hypothesized that the mass of the growing plant must come from the water, the only substance he added to the potted plant.

Although some of the steps in photosynthesis are still not completely understood, the overall photosynthetic equation has been known since the 19th century.

Jan van Helmont, a Belgian physician and chemist, is often credited with the discovery of photosynthesis in the 17th century. He conducted an experiment where he found that the increase in mass of a plant was not solely due to the uptake of soil, but also from the absorption of carbon dioxide from the air.
