KOH (Potassium Hydroxide) absorbs carbon dioxide. The leaf inside the bottle containing KOH solution does not become blue-black when compared with the leaf which is exposed to atmospheric air. This shows that carbon dioxide is necessary for photosynthesis.

Explanation:
Half-leaf experiment is a technique used to study the process of photosynthesis. In this experiment, a leaf is cut into two halves and one half is exposed to light while the other half is kept in the dark. The presence of KOH solution is important in this experiment for the following reasons:
Absorption of CO2:
KOH solution is used in the half-leaf experiment because it absorbs carbon dioxide (CO2) from the air. This is important because it helps to create a CO2-free environment around the illuminated half-leaf. This is necessary to ensure that the CO2 produced during photosynthesis in the illuminated half-leaf is not reabsorbed by the air.
Prevention of moisture loss:
KOH solution also helps to prevent moisture loss from the leaves. This is important because photosynthesis requires water, and if the leaves lose too much water, the process of photosynthesis may be affected. The KOH solution helps to maintain a moist environment around the leaves, which ensures that the process of photosynthesis is not affected by water loss.
Conclusion:
Therefore, the correct answer to the given question is option 'D'. KOH solution is used in the half-leaf experiment of photosynthesis because it absorbs CO2 from the air, which helps to create a CO2-free environment around the illuminated half-leaf. Additionally, it also helps to prevent moisture loss from the leaves, which is important for the process of photosynthesis.
