How Plants Make Oxygen
A biochemical mechanism called the water-oxidizing clock enables plants and some bacteria to exploit solar energy to split water molecules into oxygen gas, protons and electrons

The Absorption of Light in Photosynthesis
The first steps in photosynthesis are the absorption of light by a pigment molecule and the delivery of the absorbed energy to other molecules capable of entering into chemical reactions

The Role of Chlorophyll in Photosynthesis
The pigments of plants trap light energy and store it as chemical energy. They do this by catalyzing an oxidation-reduction process in which hydrogen atoms are boosted from water to organic matter
