The variegated leaf experiment helps to demonstrate the essentiality of light for photosynthesis.

Variegated leaves have patches or streaks of different colors due to variations in pigment production. Some parts of the leaf may have normal green coloration, indicating the presence of chlorophyll and active photosynthetic cells. Other parts may lack chlorophyll and appear white or pale, indicating a lack of active photosynthesis.

When conducting the variegated leaf experiment, if the green parts of the leaf produce starch while the non-green parts do not, it indicates that photosynthesis is occurring only in the green areas exposed to light. This demonstrates that light is essential for photosynthesis.

Carbon dioxide (CO2) is also essential for photosynthesis as it is one of the reactants in the process. However, the variegated leaf experiment specifically highlights the role of light in photosynthesis.
