Unit 7 - Photosynthesis and Respiration

As we discovered in the last unit, animals and plants have evolved differently. They differ on the cellular levels as well as in structure and appearance. However, plants and animals are inextricably linked and dependent on one another throughout their evolution because of two complimentary life processes - photosynthesis and respiration. In this unit we will take a close look at those two processes and how they relate to the production of energy which all living things need to live and grow.

SB3a: Explain the cycling of energy through the processes of photosynthesis and respiration.Assignment 1: Begin our study by watching the video entitled "Energy and the Chemistry of Life." Part 1 of the video is a review of the chemistry of life we touched on in the last unit. Part 2 is a detailed look at the important chemical processes we call photosynthesis and cellular respiration. Take notes and answer the questions on the Photosynthesis/Respiration worksheet as you watch. (Click here to view worksheet)




Assignment 2: Photosynthesis and Respiration - mini- lecture. Take notes, participate in class discussion, and begin to fill in the Important Vocabulary section in the Photosynthesis/Respiration worksheet as we go.

Watch following video entitled "Cellular Respiration" to review cellular respiration.



Assignment 3: Structure and Function of a Leaf -- mini-lecture. Complete the Leaf Structure and Function worksheet as we go. (Click here to see worksheet)

Recap what you learned about leaf structure and function. Watch the following videos entitled "Leaf Structure and Function" and "Transport in Vascular Plants."





Assignment 4: Review for unit quiz. To review first study the information on the worksheets. Then watch the videos attached to Assignment 2 one more time. Finally, take the following short practice quiz and discuss your answers with your instructor. (Click here to view quiz)

Quiz: Unit quiz on Photosynthesis and Respiration. Know the raw materials, products and balanced equations for photosynthesis, aerobic respiration, and anaerobic respiration as well as where in the cell and in plants these processes take place.
