PhotosynthesisPhotosynthesis is the scientific process to convert sunlight, carbon dioxide andwater into glucose and oxygen. It is one of the oldest and most fascinating processes inbiology and involves the biological conversion of light energy to chemical bond energythat is stored in the form of organic carbon compounds (Falkowski & Raven, 2007).Photosynthesis supplies the primary source of organic matter for the growth andmetabolic demands of all the other organisms in the ecosystem. Photosynthesis isdirectly related to the life and survival of all the other living creatures on earth. It doesnot just supply oxygen, without which, breathing and being alive would be difficult, but italso supplies food and energy to all (Ghosh, 2018). Photosynthesis involves two typesof reactions: light dependent reactions and light independent reactions.Light Dependent ReactionsLight dependent reactions are reactions that use light energycoming from the sunto make two molecules needed for the next stage of photosynthesis: the energy storagemolecule ATP and the reduced electron carrier NADPH. In plants, the light reactionstake place in the thylakoid membranes of organelles called chloroplasts (KhanAcademy, 2015).
