What happens during the first stage of photosynthesis?
Explanation AND reference(s): The light energy excites the electron in the reaction centres of photosystem 1and photosystem 2. It does not trap the Light Energy. During the first step of photosynthesis, the chloroplasts [which give plants their green color] capture the energy from the sunlight.
In the second step, the cell uses the captured energy (ATP to produce sugars in the form of glucose.
