Priestley experiment - explanation

Numerous cells provide oxygen production.

The experiments presented

  • Joseph Priestley led by a now very simple for us experiment in which he put a candle under a container. Shortly afterwards went from this, from which could be drawn that there is something in the air that is needed for the burn process.
  • Law similarly looked the next attempt, where a mouse was placed in the container. After also choked them, he put together mouse candle and saw that the candle went earlier and the mouse died rapidly. Whatever the two also needed for life, it was apparently the same.
  • Clear was the situation when Priestley put another mouse with a plant in the container. The small creatures could live longer.

What can be learned from Priestley

  • The experiments of Joseph Priestley were groundbreaking for the beginnings of research to photosynthesis. For today it is clear that mice, but also flames need oxygen, just as people breathe oxygen and exhale carbon dioxide.
  • Plants provide in nature that the discharge is converted back into valuable oxygen, which is necessary for human life. Described is the photosynthesis, where carbon dioxide absorbed and converted to oxygen. People, animals and even flames can breathe like that.
  • Based on the experiments of Priestley could later complete the formula to the oxygen processing. Today you know that in addition to carbon dioxide and water, sun and nutrients needed from the soil to produce oxygen.

What seems so simple can of researchers recreated world barely. Thus, the interaction between the sun and the plant is incredibly complex and perfectly matched.
