Answer: The correct answer is-
A. How plants transform light into stored chemical energy.
The given equation in the model of the represents word equation for photosynthesis.
Photosynthesis is a process of formation of food ( that is a carboydrate) in green plants and algae using CO2 (carbon dioxide) and H2O (water) in the presence of sunlight.
During this process, a green pigment in the chloroplast called chlorophyll, absorbs solar energy and converts it into chemical energy in the form of ATP and NADPH.
In the next phase, which is a light independent phase ,the chemical energy is utilized in the formation of glucose, which is a food molecule for green plants and algae.
Thus, option A) is the right answer.
