    To measure the rate of photosynthesis in the experiment, one can employ various methods. A common approach is to monitor oxygen production as a byproduct of photosynthesis. Place both groups of plants in airtight chambers, initially devoid of oxygen. Use a sensor or gas-collecting apparatus to measure the increase in oxygen concentration over time. The group exposed to sunlight should exhibit a higher rate of oxygen production, indicating more active photosynthesis. Alternatively, measure the rate of carbon dioxide uptake or starch accumulation in leaves using appropriate techniques. These quantitative assessments provide insights into the photosynthetic activity and the impact of sunlight on plant metabolism.

    Sunlight is considered essential for photosynthesis because it provides the energy needed to drive the process. During the light-dependent reactions of photosynthesis, light energy is absorbed by chlorophyll and other pigments in plant cells. This energy is used to split water molecules, releasing oxygen and generating high-energy molecules such as ATP and NADPH. These energy-rich molecules are then utilized in the light-independent reactions (Calvin cycle) to convert carbon dioxide into glucose. Without sunlight, the light-dependent reactions cannot occur, and the overall photosynthetic process is hindered, emphasizing the indispensable role of sunlight in powering the synthesis of organic molecules in plants.
