A small piece of black paper was folded in half and used to cover part of the top and bottom portions of a leaf on a living geranium plant. After the plant was kept in sunlight for several days, the paper was removed. The leaf was then boiled in alcohol to remove the chlorophyll and placed in Lugol's iodine solution. Only the part of the leaf that had not been covered turned blue black. This investigation was most likely testing the hypothesis that

Light is necesarry for photosynthesis to occur

Explanation:

Based on the information given in the question, the investigation was most likely testing the hypothesis that light is necesarry for photosynthesis to occur.

Photosynthesis, simply means the process by which green plants transform light energy into chemical energy. It should be noted that during photosynthesis, light energy is captured which is then used in the convertion of carbon dioxide and water, into oxygen and energy which comes in form of sugar.

This investigation was most likely testing the hypothesis that SUNLIGHT is necessary for photosynthesis

Explanation:

Photosynthesis can be defined as the process by which plants (green plants) use inorganic compounds such as carbondioxide and water to manufacture their own food. This process is not only important to plants but also to animals which depends on plants for food. The main features of photosynthesis include:

--> it takes place in chlorophyll of plant cells

--> Raw materials needed for this process are inorganic compounds such as carbondioxide and water

--> Final products are organic compounds such as sugar and oxygen as by product.

--> Energy needed for this process is gotten from SUNLIGHT which is absorbed by the chlorophyll.

To show that sunlight is necessary for photosynthesis, an experiment is performed as stated in the question above. Only the part of the leaf that had NOT BEEN covered turned blue black because the exposed part has been actively photosynthesizing due to the presence of SUNLIGHT. While the covered part didn't undergo any photosynthesis as it tested negative for starch when placed in Lugol's iodine solution.
