Answer : The light reaction of photosynthesis changes the energy of the sun into chemical energy.
Explanation :
Photosynthesis : It is a chemical process in which occurs in the green plants or living organism. During this process, the carbon dioxide reacts with water in the presence of sunlight to gives glucose and oxygen as a product.
Photosynthesis takes palace in two steps which are light reaction and dark reaction.
Light reaction : It is the first step of photosynthesis in which the water is broken in the chlorophyll molecule into hydrogen ion and hydroxide ion in the presence of light.
Dark reaction : It is the second step if photosynthesis in which the chemical process of photosynthesis takes palace in the absence of light.
Hence, the light reaction of photosynthesis changes the energy of the sun into chemical energy.
