Photosynthesis: Using Light to Make Food Chapter Objectives Explain how plants can be used as a renewable energy source. Explain why this is better than burning fossil fuels. 7.1 Define autotrophs, producers, and photoautotrophs. 7.2 Describe the structure of chloroplasts and their location in a leaf. Identify specifically where most light energy is converted to chemical energy. 7.3 Explain how plants produce oxygen. 7.4 Describe the role of redox reactions in photosynthesis and cellular respiration. 7.5 Compare the reactants and products of the light reactions and the Calvin cycle. Explain how photosynthesis relates to these reactions. 7.6 Describe the properties and functions of the different photosynthetic pigments. 7.7 Explain how photosystems capture solar energy. 7.8–7.9 Explain how the electron transport chain and chemiosmosis generate ATP, NADPH, and oxygen in the light reactions. 7.9 Compare photophosphorylation and oxidative phosphorylation. 7.10 Describe the reactants and products of the Calvin cycle. Explain why this cycle is dependent upon the light reactions. 7.11 Review the overall process of the light reactions and the Calvin cycle, noting the ­products, reactants, and locations of every major step. 7.12 Compare the mechanisms that C3, C4, and CAM plants use to obtain and use carbon ­dioxide. Note examples of plants that use each of these systems. 7.13 Describe the greenhouse effect. Explain how deforestation and the use of fossil fuels contribute to global warming. 7.14 Explain how the ozone layer forms, how human activities have damaged it, and the ­consequences of the destruction of the ozone layer.
