prove by the experiment carbon dioxide is necessary for photosynthesis. and matter also
Answers
Answer:
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
Answer:
EXPERIMENT TO PROVE THE NECESSITY OF CARBON DIOXIDE IN PHOTOSYNTHESIS -
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.
