Absorbed Light in Photosynthesis

Photosynthesis consists of two simultaneous processes that produce food for an organism like a plant. There is a process involved with light reactions and there is a process called the Calvin Cycle. The light reaction converts solar energy to chemical energy that a plant uses to maintain homeostasis. Chloroplasts are the regions in the mesophyl cells that contain thylakoids transform light energy to the energy of ATP. The following is a Chloroplast's thylakoid:

The sun is powered by four hydrogen atoms that bond to form a helium atom. When these four atoms fuse together the mass of the helium atom is slightly less than the mass of merely four hydrogen atoms added together. Therefore, this lost mass has been converted to energy which follows the equation founded by Einstein E=mc^2. On the sun there are about 120 million tons of solar matter converted into energy every minute and only a fraction of this energy travels to the Earth.

Light behaves as a wave and as a particle. Its wavelike properties are described by the electromagnetic spectrum. The electromagnetic spectrum is described by all the colors in the rainbow and also invisible radiation such as gamma rays and x rays. The following is the electromagnetic spectrum. They vary in due to their wavelength. The atmosphere acts as a filter to eradicate certain forms of radiation by the sun allowing life to survive on Earth. Radiation in the visible light, mainly blue and red contribute in the photosynthesis of plants.

Light also behaves as if it consists of individual particles called photons. Wavelength is inversely related to the amount of energy in photons. When a molecule absorbs a photon, one of it's electron's is elevated to an orbital where it contains more potential energy(elevated state from a ground state). The electron temporarily is in this high state of potential energy and due to instability this potential energy is converted into heat. This is why cars become hot in the sun because their individual electrons are elevated from photons and then returned to a ground state finally releasing heat.
