Joseph Priestley was another scientist who contributed to the discovery of photosynthesis. He was born in and later became a chemist, minister, natural philosopher, educator and political theorist. His experiments included placing a lit candle inside a closed jar. Jan Ingenhousz also contributed to the discovery of photosynthesis. He was a Dutch chemist, biologist and physiologist who performed important experiments in the late s that proved that plants produce oxygen. 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. In , Jean Senebier, a Swiss botanist, pastor and naturalist demonstrated that plants absorb carbon dioxide and release oxygen with the help of sunlight.
He proposed that plants convert light energy into chemical energy. Enthalpy Question -- Hess' Law was created because a calorimeter can't be used to measure the enthalpy variation of some reactions?

Is there some sort of natural fiber optic system which transports the absorbed light to the photosynthetic organelle?
Is there a preliminary chemical process which creates a photosynthesis precursor enzyme or building block which in turn is shipped to the organelle via known mechanisms? Does the light just bounce haphazardly around inside the interstitial fluid medium until it collides with the photosynthesis machinery?
