A green leaf is partially covered and placed in the light for several days. If it is then boiled and tested for starch with iodine, what will be the result?

A
Starch will be found only in the part of the leaf exposed to light
💡 Explanation:
The leaf on the right shows a positive test for starch in the areas which contained chlorophyll, and a negative test for starch in the areas which lack chlorophyll. This is evidence that chlorophyll is required for photosynthesis. A plant can be 'de-starched' by leaving it in the dark for a few hours.
So, the correct option is "C" (Starch will be found only in the part of the leaf exposed to light).
