Question

The following diagram demonstrates a physiological process taking place in green plants. The whole set up was placed in bright sunlight for several hours. Study the diagram and answer the question that follow.

What aspect of the physiological process is being examined?

Answer 1

The given experiment demonstrates that oxygen is evolved during the process of photosynthesis. In this experiment, the aquatic plant-like Hydrilla is used. The aspect is the light reaction of photosynthesis. This is the process in which the plants with the help of chloroplast captures light energy. They can use the carbon dioxide from the air to produce carbohydrates in the form of sugar and starch. There is a splitting of water to fill the gap created by the electron in the photosystem. The product which is formed is oxygen which is liberated during this process.
