Photosynthesis and the Energy of Life

Chapter 8Biology

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
