Biology Homework Chapter 7: Photosynthesis - the Calvin Cycle and CAM Pathways


Reading Preparation

Textbook assignment: Chapter 7: Photosynthesis: Using Light to Make Food, sections 10-14.

Study Notes

Web Lecture

Read the following weblecture before chat: Dark Reactions

Take notes on any questions you have, and be prepared to discuss the lecture in chat.

Study Activity

Perform the study activity below:

Use the OLABS Importance of Light in Photosynthesis lab simulation to explore how the amount of light changes the rate of photosynthesis.

  • Read the theory tab.
  • Read the lab procedure tab on how the simulator works.
  • Watch the animation so that you understand the procedure.
  • Use the simulator to run the experiment several times. Change only one factor at a time, but record how many bubbles are produced for 30-second or one-minute intervals if you
    • Change the wattage on the light.
    • Change the distance between the plant and the light.
    • Change the color filters on the light.

Is it possible to have too much light? Is one color filter better than another? How can you explain your results?

Optional Website: There is a more detailed discussion of the Calvin Cycle reactions in J. Kimball's biology pages, and another good summary of the individual dark reactions produced by Academic Television Services.
