Question

Describe the experiment showing that carbon dioxide is necessary for photosynthesis.

Answer 1

Answer:

Image result for describe the experiment showing carbon dioxide is necessary for photosynthesis

Experiment to prove the necessity of carbon dioxide in photosynthesis - definition. 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.

Observation-

Observation-Leaf exposed to the atmosphere are bluish black.

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.
