One of the major claims being made surrounding "A" of the light reaction model is that light energy is absorbed by chlorophyll and used for the hydrolysis of water and to create a concentration gradient of hydrogen ions? How could you test the idea that solar energy is required for the hydrolysis of water during photosynthesis?

The information regarding the solar energy should be explained below;

The following information should be considered:

You can test the idea that solar energy is necessary for the hydrolysis of water during photosynthesis, keeping a plant with access to the sun and a plant without access to the sun, equally watered and see how the two plants keep up.

Explanation:

As you may already know, water is extremely important for photosynthesis, which is very important for plant growth and survival. Without photosynthesis the plant dies and without hydrolysis of the water the plant does not perform photosynthesis.

As we know the role of solar energy in photosynthesis is to provide hydrolysis of water, to test whether this is true you can plant two equal plants with the same soil, the same fertilizer and the same amount of irrigation, where one of these plants will be kept in one environment where it receives full sunlight and the other will be kept in an environment without any individual sunlight. You should analyze the development and growth of the plants, as the only difference between them is the incidence of sun, if the plant that is in the sun develops well while the plant that is in the shade does not develop well is because the sunlight is really important to cause the hydrolysis of water and the initiation of photosynthesis.
