Solution

All green plants have photosynthetic reaction centers, and they’re also found in many types of algae, as well. Essentially, these are proteins that contain chlorophyll and other co-factors, as well as receptors capable of capturing photons of light.

As photons are captured, an electron within the pigment (chlorophyll) is excited (gains more energy). As the electron becomes more excited, it generates more energy, which is then available to the plant for use in metabolic processes.

Specifically, the energy collected from excited electrons is used to generate ion and pH gradients. These are necessary for ATP synthesis needed in most green plants. It also helps with the conversion of CO2 into sugars, and the extraction of energy from those substances.
