In the experiment to prove that light is necessary for photosynthesis, which one of the following is not required and why? a) Alcohol b) Iodine c) KOH d) Water

Dear student.

The correct answer is KOH.

KOH is used in the experiment to show that carbon dioxide is necessary for photosynthesis is as follows where a part of a leaf is enclosed in a test tube containing some KOH soaked cotton, which helps in absorbs CO2. The carbon dioxide is absorbed so that no carbon dioxide is left in test tube.

Rest all are required in the experiment to prove light is essential for photosynthesis.

Regards.
