Verified step by step guidance1
Understand the process of photosynthesis, which is the method by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.
Recognize that photosynthesis occurs in two main stages: the light-dependent reactions and the light-independent reactions (Calvin cycle).
Identify that the first step in photosynthesis is the absorption of light by chlorophyll molecules located in the chloroplasts of plant cells.
Learn that when chlorophyll absorbs light, it becomes excited and initiates a series of reactions that convert light energy into chemical energy.
Note that this light absorption is crucial as it sets the stage for subsequent processes like glucose synthesis, oxygen release, and carbon fixation.
