Answer» Answer: EXPERIMENT TO PROVE THE NECESSITY OF CARBON DIOXIDE IN PHOTOSYNTHESIS - DEFINITION 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.

Answer:

EXPERIMENT TO PROVE THE NECESSITY OF CARBON DIOXIDE IN PHOTOSYNTHESIS - DEFINITION

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.
