Question

Choose the correct answer from the alternatives given.
Molls experiment demonstrates the necessity of which of the following in photosynthesis

• A. water
• B. oxygen
• C. carbon dioxide
• D. chlorophyll

The correct option is C carbon dioxide

Molls experiment evidently shows that plants do not form starch when carbon dioxide is not at their disposal, all the carbon dioxide contained in the bottle having been absorbed by the caustic potash solution.

Thus, the correct answer is 'Carbon dioxide.'
