What did Jan Ingenhousz show?
He proved that Priestley's experiment only worked when plants were exposed to sunlight. Concluding that Priestley had not performed his experiment without sunlight. Ingenhousz performed both in sun and dark presence.
How were Priestly's and Ingenhousz's discoveries about photosynthesis related?
Priestley discovered that plants released oxygen during photosynthesis, while Ingenhousz demonstrated that this process only occurred in the presence of sunlight. Together, their findings established the role of sunlight in the process of photosynthesis, with Priestley's work on oxygen production and Ingenhousz's work on the light-dependent nature of the process.
How were Priestley's and Ingenhousz' discoveries about photosynthesis related?
Priestley discovered that plants release oxygen in the presence of light, while Ingenhousz found that plants only release oxygen in the presence of both light and green parts of the plant. Together, their discoveries laid the foundation for understanding photosynthesis as the process by which plants use light energy to produce oxygen and convert carbon dioxide into carbohydrates.
Which scientist showed that light was needed for photosynthesis to happen?
In 1796 a Swiss botanist, Jean Senebier, showed that plants consume carbon dioxide and produce oxygen in the presence of light. His research was preceeded by the research of others who led the way to the final discovery.
The early suggestion that oxygen liberated from plants during photosynthesis comes from water was?
The early suggestion that the oxygen (O2) liberated from plants during photosynthesis comes from water was first published by Melvin Calvin, who also discovered the Calvin cycle. It was confirmed by experiments using oxygen-18 (18O).
Ingenhousz showed that plants produce oxygen bubbles when exposed to?
Light

What did Jan do?
Jan Ingenhousz concluded from his experiments that all plants need sunlight to produce energy. He also concluded that plants underwater only produce oxygen bubbles when they have access to sunlight.
Who showed that plants produce oxygen when exposed to light?
Jan Ingenhousz

Who discovered that plants add oxygen to air?
Jan Ingenhousz, a Dutch scientist, is credited with discovering that plants release oxygen during photosynthesis. His experiments in the 18th century demonstrated that plants produce oxygen in the presence of sunlight.
What did Jan ingenhousz?
Jan Ingenhousz was a Dutch-born English scientist who is credited for the discovery of photosynthesis. It is the process wherein green plants absorb carbon dioxide and sunlight in order to release oxygen.
How do you think ingenhousz showed that it was dephlogisticated and not fixed air?
Ingenhousz demonstrated that oxygen (dephlogisticated air) was produced during photosynthesis by showing that plants release this gas in the presence of light. This was different from fixed air (carbon dioxide) because plants were observed to only release oxygen in the light, suggesting a direct relationship between the presence of light and the production of oxygen.
Why does hydrilla produce bubbles?
the hydrilla produce bubbles when added baking soda because, the bubbles are the oxygen that the hydrilla produce, while it undergoes the process of phtosynthesis in the water.
Which scientist showed that light was needed for photosynthesis to happen?
In 1796 a Swiss botanist, Jean Senebier, showed that plants consume carbon dioxide and produce oxygen in the presence of light. His research was preceeded by the research of others who led the way to the final discovery.
What was Jan ingenhousz hypothesis of photosynthesis before doing the experiment?
Jan Ingenhousz hypothesized that plants produce oxygen during photosynthesis. He also proposed that the green parts of plants play a crucial role in this process.
