Chapter 8 Outline
Photosynthesis
Photosynthesis, which takes place in chloroplasts,
includes the light-dependent reactions when solar energy is captured,
and the light-independent reactions, during which carbohydrates
are synthesized through the Calvin cycle. C4 photosynthesis and
CAM photosynthesis are also included.
Chapter Outline
In this chapter outline, the learning objectives
and the selected key terms are given for each major head in the
chapter.
1. Give at least three examples of the importance of photosynthesis to living things.
Selected Key Terms: photosynthesis
Sunlight Is Solar Energy (p. 120)
2. Describe the electromagnetic spectrum and the absorption spectra for chlorophylls aandb.
photons, electromagnetic spectrum
Photosynthesis Occurs in Chloroplasts (p. 122)
3. Describe the structure of chloroplasts, and give the function of the two main parts.
4. Explain the terms light-dependent reactions and light-independent reactions, and describe how the light-dependent reactions drive the light-independent reactions.
chloroplast, stroma, grana, thylakoid, chlorophyll, light-dependent reaction, light-independent reaction
Solar Energy Is Captured (p. 124)
5. Trace the cyclic electron pathway, pointing out significant events.
6. Trace the noncyclic electron pathway, pointing out significant events.
7. Describe the process of chemiosmotic ATP synthesis in chloroplasts.
8. Name four complexes (particles) within the thylakoid membrane, and give a
function for each.
photosystem, electron transport system
Carbohydrate Is Synthesized (p. 127)
9. Describe the three stages of the Calvin cycle.
Calvin cycle, RuBP (ribulose bisphosphate),carbon dioxide (CO2) fixation
Photosynthesis Takes Other Routes (p. 130)
10. Contrast C3 and C4 plants, and relate the phenomenon of photorespiration to the success of C4 plants in hot, dry climates.
11. Contrast a CAM plant with a C4 plant, using the terms partitioning in space and partitioning in time.
C3 plant, C4 plant, CAM plant
