Oxygen is a by product of Photosynthesis
Hello everyone! Today we are going to learn about an experiment which will prove Oxygen is a by product of the process photosynthesis.
Experiment:
The experiment which proves that Oxygen is a by product of Photosynthesis is known as the Priesley's Experiment
Aim - To prove Oxygen is a by product in the process Photosynthesis.
Apparatus - 1. A Mouse or Rat
2. A Candle
3. A jar
4. A small plant which will do the Photosynthesis
Procedure - 1. Take a small rat and place it in a closed jar
2. Light the candle and place it in the closed jar.
3. Then, if you see it after some time, the candle will off and the rat will die.
-
1. Now, also take a small rat and place it inside the jar.
2. Light the candle and place it in the closed jar.
3. Now, along with the candle and the rat place a small tree
4. Then, if you observe it after some time also, the rat not die and the candle will not off.
Observation - First we all know that animals (Including rats) and candle will need oxygen to survive. Here, inside the jar the little oxygen also the candle and the rat will use it. So, after some time there will be no oxygen left for the rat to breath and the candle to be lighted. Eventually, the rat will die and the candle will not burn and off.
But, if you see in the second part, they will place a small plant with it. Now if you see after some time the rat will survive and the candle will be lighted. It is because, plants which does the photosynthesis will give out oxygen as a by product. So, because of this, the candle and the rat will give out carbon dioxide and the plant will take in the carbon dioxide. Then, the plant will give out oxygen which will help the candle to be lighted and the rat to be alive.
Thank you!
