Question

Why do we add KOH in the bottle in the experiment to demonstrate that carbon dioxide is required for photosynthesis?​

Answer 1

Answer:

here is ur answer

The 'germinating seeds' are used because they take up the oxygen present inside the flask to 'respire' and release 'carbon-di-oxide' which will be absorbed by KOH. This cause the KOH weight to increase. By this process the carbon dioxide is completely made unavailable to plant in photosynthesis reaction.

hope it helps u

Answer 2

Answer:

We add potassium hydroxide (KOH) in the bottle in the experiment to demonstrate that carbon dioxide is required for photosynthesis as it absorbs carbon dioxide from the bottle and there is no carbon dioxide left in the bottle.
