Detailed explanation-1: -One of the vital pigments in plants that efficiently participate in light reactions is chlorophyll. The chlorophyll will get activated by the sunlight and split water molecules. When a water molecule is split, oxygen, hydrogen, and electrons are produced.

Detailed explanation-2: -A molecule of water splits to release an electron, which is needed to replace the one donated. Oxygen and hydrogen ions are also formed from the splitting of water. The replacing of the electron enables chlorophyll to respond to another photon.

Detailed explanation-3: -The replacement of the electron enables chlorophyll to respond to another photon. The oxygen molecules produced as byproducts exit the leaf through the stomata and find their way to the surrounding environment.

Detailed explanation-4: -The light-dependent reactions convert light energy into chemical energy, producing ATP and NADPH.

Detailed explanation-5: -Photosynthesis vs. In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct.
