The thylakoids of the chloroplast are responsible for the light reactions that occur within plants. All organisms that perform photosynthesis have chlorophyll A, but not all organisms contain chlorophyll B. Chlorophyll A absorbs light from the orange-red and violet-blue areas of the electromagnetic spectrum. This happens when energy from a photon (light) removes an electron from chlorophyll in reaction center P680 of photosystem II. Chlorophyll's role is to absorb light for photosynthesis. The two photosystems work together continuously. Algae and non-vascular plants don't require light to synthesize chlorophyll. It is the primary pigment in photosynthetic plants. Water provides the electrons and hydrogen ions needed to power the light-dependent and light-independent phases of photosynthesis. It is mixed with a small amount of oil when it's used in food. Two long, straight parallel wires 8.6cm8.6 \mathrm{~cm}8.6cm apart carry equal currents. The hydrogen is taken (ETC) to the stroma by NADPH along with the grana's remaining light energy. This is where photosynthesis takes place. As the pH rises (becomes alkaline), the solution returns to red. Phytochrome. The energy absorbed from light is transferred to two kinds of energy-storing molecules. Absorbs light energy and converts it into chemical energy. Carotenoids are a class of phytonutrients ("plant chemicals") and are found in the cells of a wide variety of plants, algae and bacteria. 8 What is the role of photosynthesis to plants?
