Welcome to Module 5

Greetings,

This week's assignments will cover Chapter 7 - Photosynthesis - Using Light to Make Food. This chapter begins our material for the final examination.

For this week's assignments, you will complete the chapter reading, homework, Dynamic Study Module, and an interactive lab on photosynthesis. Please review the syllabus for start and due dates, as well as the late assignment policy.

The learning objectives in this chapter can be used as a guide for your quiz and exam. I will mail you the PPTs for the chapter in your Canvas email.

As always, please contact me if you have any questions.

Module Learning Outcomes

Upon successful completion of this module, you will be able to:

An Introduction to Photosynthesis

7.1 Define and distinguish between autotrophs, heterotrophs, 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. Describe the experiments that revealed the source of the oxygen produced during photosynthesis.

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.

The Light Reactions: Converting Solar Energy to Chemical Energy

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 Relate the structures within the thylakoid membrane to the steps of photophosphorylation.

The Calvin Cycle: Reducing CO2 to Sugar

7.10 Describe the reactants and products of the Calvin cycle. Explain why this cycle is dependent on the light reactions.

7.11 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.

The Global Significance of Photosynthesis

7.12 Review the overall process of the light reactions and the Calvin cycle, noting the reactants, products, and locations of every major step.

7.13 Explain how rising carbon dioxide levels may affect plants.

7.14 Describe the greenhouse effect. Explain how fossil fuel consumption and deforestation affect climate change.
