Photosynthesis occurs in two stages. The chloroplasts use photosynthetic chlorophyll pigment and take in sunlight, water, and CO2 to produce glucose and oxygen. Chlorophyll absorbs the vast majority of red and blue light. 42. It is mixed with a small amount of oil when it's used in food. Why is it said that abundance of life on earth wouldn't exist if we didn't have plants? C. Stems. Chlorophyll is the name given to a group of green pigment molecules found in plants, algae, and cyanobacteria. The two photosystems work together continuously. (a) Absorb carbon dioxide from the atmosphere. Chlorophyll can absorb all the wavelengths of light in the visible spectrum except for the green wavelengths. Stomata are pores found on the leaf through which carbon dioxide enters and oxygen exits the leaf. Because of the increased chlorophyll content, the plant can convert more of the energy from the sun into chemical energy. E. Turn clear. A student set up a test tube containing sodium bicarbonate and topped it with a volumeter, but forgot to add the Elodea plant! Yellow-orange. Based on a variety of experiments, it is known that the rate of photosynthesis is highest when wavelengths of light between 400 and 500 nm are used, and when wavelengths around 700 nm are used. These plants are pale if they are grown in darkness because they can't complete the reaction to produce chlorophyll.
