What is the experiment to prove that oxygen is released during photosynthesis?

Answer 1

In 1770, Joseph Priestly conducted experiment to discover one of the products of photosynthesis. He first put a mouse into a bell jar and left it, it died. He then put a burning candle into the bell jar and it burnt out. After that, he placed a plant into the bell jar with another mouse, it survived! And, then he placed a candle in with the plant, it didn't burn out! So using our knowledge of respiration and combustion we know that you need oxygen to burn and oxygen to respire.

Answer 2

Photosynthesis is the process by which plants make their own food. In the process the following inputs are needed water and carbon dioxide, in the process of making their food a reaction is happening converting CO2 and H20 to sugar (glucose), Oxygen is the other product.

Answer 3

One method would be to place some type of water plant in a clear beaker full of water. Have a light plugged in which is pointing towards the plant. As the plant photosynthesises, you will be able to see the oxygen produced as bubbles rising to the top of the beaker.

Answer 4

by using hydrilla we can prove that oxygen is evolved in photosynthesis

Answer 5

Actually photosynthesis does not require oxygen. Carbon dioxide and water are required and oxygen is a by-product of photosynthesis.
