Photosynthesis nourishes almost all of the living world directly or indirectlyCampbell 1993 It is the process used by certain organisms to trap light energy and convert it to chemical bond energy forming organic compounds Vliet 1993 Chloroplasts are the sites of photosynthesis All of the green parts of a plant have chloroplasts but the leaves are the major site of photosynthesis Campbell 1993 Chloroplasts are made up of four major internal membranes They are arranged in layers called lamellae which fuse in some places to form disk-like sacs called thylakoids Vliet 1993 Thylakoids are stacked in columns called grana Vliet 1993 The cytoplasm surrounding the grana is called stroma Vliet 1993 The light reactions occur in the thylakoids the dark reactions occur in the stroma Vliet 1993 Photosynthesis can be broken down into two categories light and dark reactions Basically light reactions require light from the sun and dark reactions are not dependant on light Light reactions result in the production of adenosine triphosphate ATP nicotinamide adenine dinucleotide phosphate NADPH and oxygen at the expense of water and light energy Vliet 1993 The dark reactions utilize the energy trapped within the ATP and NADPH produced in the light reactions to convert carbon dioxide to glucose Vliet 1993 On the surface of the thylakoids are photosynthetic pigments which are bound to proteins embedded within the thylakoid membrane Vliet 1993 Pigments are substances that absorb visible light Campbell 19993 Pigments do not absorb all wavelengths the equally Green light is reflected and red and blue are most effectively absorbed by the pigments The wavelength important to life that ranges from 380 to 750nm is the visible spectrum The wavelength of is important to absorption and the energy of visible light As the wavelength of light increases the energy decreases In this experiment we will test to see which wavelengths give the best reaction rates and also we will determine what intensities are optimal for plants
