Question

ident (P.No: 7) Light and Photosynthesis. (A.S-4) a) In Priestley's time, scientists didn't understand about energy, but later on much was discovered about it. If energy is released when carbon dioxide and water is formed by combining oxygen with carbon and hydrogen then what about the reverse ? b) What about forming oxygen again and putting it back in the air ? c) Eventually, scientists learned that the energy situation would also reverse. Oxygen formation would use up energy that means if plants form oxygen they have to get energy to make it possible. Where did the energy come from? (P.No: 7) Hydrilla experiment. (A.S-3)​

Answer 1

Answer:

Experiment to Prove the Importance of Carbon Dioxide in Photosynthesis

Materials Required: A healthy potted plant, a wide-mouthed glass bottle with a split cork, potassium hydroxide solution (KOH), and starch solution.
