Photosynthesis and the Energy of
Life
Chapter 8
Biology
Overview of the Week
• Topic: Photosynthesis
• Key concept questions:
– What is the role of ATP in the building up and
breaking down of macromolecules?
– What is the role of photosynthesis in making
carbohydrates?
• Text-study pages 45-46 (carbohydrates); 206
(the photosynthesis equation); 208-213 (The
reactions of photosynthesis section
Methods and Data sources
• There are many uses of models in this chapter.
Explain how scientists used the following
models to understand ATP
– Figure 8-2
– Figure 8-3
– Figure 8-4
– Figure 8-5
Methods and Data Sources
• Microscopes were also used in this section.
Tell how scientists used microscopes to
understand the plant structures related to
photosynthesis.
– Figure 8-6
Data Analysis
• Carbohydrates (45-46)
– Explain the structure of carbohydrates and then
explain how they are made.
• Inside a chloroplast (208)
– Explain how the structure and function of chloroplast
are related to photosynthesis.
– Tell how ATP is made within the chloroplast
• Electron carriers (209)
– Tell (in 3 sentences) how electron carriers are made
and their significance in making carbohydrates
Data analysis
• Light dependent reactions (210-211)
– Explain what the light dependent reactions are
– Tell where they occur in the chloroplast
– Tell how much ATP is made and how it is used in
the processes of the light dependent reactions
– Tell why the light dependent reactions have to
occur in order to make carbohydrates
Data analysis
• Calvin Cycle (212-213)
– Explain what the Calvin cycle is and why its
termed the dark reactions.
– Tell where the Calvin cycle takes place in the
chloroplast.
– Tell how ATP is used in the process of the Calvin
Cycle.
– Tell why the Calvin Cycle has to occur in order to
make carbohydrates.
Findings and summary
• Findings:
– Answer you five key concept questions in
complete sentences.
– Make sure you questions are at least at the
comprehension level.
• Summary
– Summarize the functions of each of the organelles
– Draw a model of a eukaryotic cell and include all
of the organelles needed for protein synthesis
