Chlorophyll a Chlorophyll b 400 450 500 550 600 650 700 Wavelength (nm) Plant chlorophyll chemicals will absorb, or take in, light wave energy in order to produce their own organic molecules used for cellular energy. Reflected light refers to those wavelengths of light that will "bounce off" of the chlorophyll and not be absorbed. Select the conclusion that most accurately summarizes the data in diagram 3. Red and blue light waves have equal importance during photosynthesis. The majority of light energy is attained from red light, while the blue light waves provide additional light energy to photosynthesis. The majority of light energy is attained from blue light, while the red light waves provide additional light energy to photosynthesis. Medium length light waves are important to photosynthesis AbsorptionUnder what conditions does plant tissue experience lack of oxygen?

The events of the light dependent cycle that take place along the thylakoid membrane are shown. Identify an energy transfer that takes place n Diagram 4. Light energy is directly transferred into the chemical bonds of sugar. O Light energy is directly transferred into the chemical bonds of ATP The energy of the bonds of water are transferred into the chemical bonds of ATP. The energy from an excited electron is transferred into the chemical bonds of NADPH.ATP is produced when protons (H+) flow down the gradient through the H+ channel/ATP synthase in the thylakoid membrane. A researcher discovers a drug that slows down the passage of protons through the H+ channel/ATP synthase. What is expected to happen if this drug is applied to the chloroplasts? The pH in the chloroplast stroma will increase, and less ATP will be produced. The pH in the chloroplast stroma will decrease, and less ATP will be produced. The pH in the chloroplast stroma will increase, and more ATP will be produced. The pH in the chloroplast stroma will decrease, and more ATP will be produced.Plant cells can perform both photosynthesis and cellular respiration. These two processes depend upon each other. Describe in detail the relationship between water and oxygen gas in plant cells. Include a description of the processes in which each is used and give the name of the organelle where each of these processes occurs.
