Answer 2

Step-by-step explanation:

To prove the necessity of carbon dioxide in photosynthesis following steps need to do

Insert a part of the leaf of a destarched plant into a conical flask containing potassium hydroxide.

Potassium hydroxide solution absorbs the carbon dioxide gas from the air present in the glass bottle.

Leave the plant sunlight.

After few hours, perform a starch test to this and another leaf of the same plant.

Observation-

Leaf exposed to the atmosphere are bluish black.

Leaf exposed to KOH does not change to blue-black colour

Result- Starch is present in the green part of the leaf.

Conclusion- Presence of starch proves that chlorophyll is necessary for photosynthesis as it traps sunlight.
