Learning Objectives

  1. Write an overall summary of photosynthesis, using only the terms carbon dioxide, chlorophyll, light, oxygen, sugar, and water.
  2. Summarize the events of the light-dependent and the light-independent reactions of photosynthesis.
  3. Explain the significance of the absorption spectrum of chlorophyll a relative to energy utilization in photosynthesis.
  4. Know all the terms in bold print in the Introduction.



Do the lab on photosynthesis found after the assignment below.


Complete the postlab questions on the photosynthesis lab after this page in the syllabus.

* Postlab questions must be typed and saved as a document with no spaces or special characters in the filename before submitting them in WebCT for a grade. Make sure you include each question before you type the answer.

Observing Oxygen Evolution During Photosynthesis



On your own paper answer the following:

1. Results from the table and perform the calculations.


Tube 1

Tube 2

net photosynthesis

(mm/10 min x 6)



aerobic respiration

(mm/10 min x 6)



gross (total) photosynthesis

(mm/10 min x 6)



2. What difference, if any, was there between the results in Tube 1 and Tube 2?

3. Why was there such a difference?
