Jan Ingenhousz | Biography, Experiments, & Facts | Britannica
Dutch-born British physician and scientist Jan Ingenhousz published the results of his study on the chemical effects of plant physiology, including his observations about photosynthesis, in Experiments upon Vegetables, Discovering Their Great Power of Purifying the Common Air in Sun-shine, and of Injuring It in the Shade and at Night, in 1779.
Jan Ingenhousz: Scientist Who Discovered Photosynthesis
2019年2月21日 · Jan Ingenhousz (December 8, 1730 - September 7, 1799) was an 18th century Dutch physician, biologist, and chemist who discovered how plants convert light into energy, the process known as photosynthesis. He is also credited with discovering that plants, similar to animals, undergo the cellular respiration process.
What did Jan Ingenhousz discover about photosynthesis?
Dutch-born British physician and scientist Jan Ingenhousz discovered that light is necessary for photosynthesis. This observation built upon work begun by English scientist Joseph Priestley, who had burned a candle in a closed container until the air within the container could no longer support combustion. Priestley then placed a sprig of mint ...
Jan Ingenhousz - Wikipedia
Jan Ingenhousz FRS (8 December 1730 – 7 September 1799) was a Dutch-British [1] physiologist, biologist and chemist. He is best known for discovering photosynthesis by showing that light is essential to the process by which green …

Joseph Priestley, England, discovers that plants can “purify” air that has been “burned out” by a candle. Jan Ingenhousz, The Netherlands, demonstrates that the plant in Priestley’s experiment is dependent on light and its green parts. Several researchers show that carbon dioxide and water are stored as organic matter by plants.

2018年5月23日 · In 1778 Ingenhousz conducted experiments on plant production of oxygen. He showed that the green leaves of plants must be exposed to substantial daylight for oxygen production to occur. From this result, he was able to counter the arguments and statements of his contemporary chemists regarding the source of oxygen.

2021年10月23日 · Ingenhousz did over 500 experiments in the summer months of 1779, working morning until night. He discovered that plants need sunlight to convert “bad air” to “good air”, or in modern terms, covert carbon dioxide to oxygen.

2024年5月18日 · Jan Ingenhousz and Jean Senebier found that the air is only reviving in the day time and that CO 2 2 is assembled by plants. Antoin-Laurent Lavoiser found that “revived air” is a separate gas, oxygen. But what is the oxygen “maker”? There are many pigments in plants, and all accept and reflect some parts of rainbow.
Jan Ingenhousz is yet another scientist who contributed to the discovery of photosynthesis. He was a Dutch chemist, biologist and physiologist who performed important experiments in the late 1770s that proved that plants produce oxygen. Ingenhousz placed submerged plants in sunlight and then in the shade.
Jan Ingenhousz and the Principles of Photosynthesis
On December 8, 1730, Dutch physiologist, biologist and chemist Jan Ingenhousz was born. He is best known for showing that light is essential to photosynthesis and thus became one of the scientists who significantly contributed to the discovery of photosynthesis. He also discovered that plants, like animals, have cellular respiration.
