Answer 1

Work with photosynthesis. In the 1770s Ingenhousz became interested in gaseous exchanges of plants. He did this after meeting the scientist Joseph Priestley (1733–1804) at his house in Birstall, West Yorkshire, on 23 May 1771. ... He also discovered that, in the dark, plants give off carbon dioxide.

Answer 2

Priestly conducted a sequence of experiments to demonstrate that what animals where doing to the air was reversed by the plants.A according to him,if the animals were doing the air impure,the plants were doing it pure.Ingenhouz tried to repeat the Priestley's experiments and found that the green parts of plants were doing something.Several scientists were doing that what green plants were doing with water and air and sunlight and till date we know that.Green plants use carbon dioxide in the presence of sunlight along with water to make starch and glucose and other food materials and this process is called photosynthesis and such plants are called Autotrophs
