Light is a form of energy that travels through electromagnetic waves. Light can either be absorbed, reflected, or refracted. Light is necessary in photosynthesis as it absorbed by the chloroplast and it excites electrons of the atoms in the thylakoid. The excited electrons then release energy when they go back to ground state in the electron transport chain where the energy is used to change ADP into ATP and perform photolysis which products are needed to create glucose in the Calvin cycle. Photosynthesis is important to life on earth because one product of the reaction is oxygen that is reactant in cellular respiration that is needed to be performed by most living organisms. Also plants being to perform to photosynthesis and other processes that are needed to survive are important because plants support the majority of all food chains on earth and without them life would be near to impossible to continue. Carbon dioxide is a one reactant of photosynthesis and without it the process couldn’t take place. In addition, if there’s an increase of carbon dioxide in the air or soil surrounding the plant then photosynthesis occurs at a more rapid pace. Photosynthetic pigments absorb different colors of visible light that is needed to perform photosynthesis. The goal of the first experiment was to see that carbon dioxide is absorbed during photosynthesis. The goal of the second experiment was to learn how to extract photosynthesis pigments from a leaf. The goal of the third…
