Question

The aim behind Moll's half-leaf experiment was

• A. CO${}_2$ is produced during anaerobic respiration
• B. CO${}_2$ is produced during aerobic respiration
• C. CO${}_2$ is necessary for photosynthesis
• D. Chlorophyll is necessary for photosynthesis

Answer 1

Answer: (C)

CO${}_2$ is necessary for photosynthesis

Moll's half-leaf experiment was done to show that plants cannot photosynthesize unless carbon dioxide is available. Plants use sunlight and carbon dioxide present in air to produce food for itself, in the absence of either photosynthesis is affected adversely.

So, the correct answer is option C.
