This course concerns those aspects of earthly environment that plants interact and respond to.  It is most concerned with how plants have evolved to sense and respond and adapt to changing environmental challenges in order to survive and reproduce.  The outcome being that plants (along with some bacteria) produce the food for all life on earth.  The most abundant protein found on earth is Rubisco, the enzyme that converts CO2 to sugar.  Because plants themselves are food for other species and because they are sessile for the most part, they have evolved ingenious strategies of interaction and survival.  This course explores some of these wonders of plant existence.




Requirements and pedagogy for this course may change.  Input from YOU is important for shaping the course.   Please input to the class and me often.

          1. 20% Exam/quiz   1 in class exam after midterm or 6-7 in-class 15min

                    quizzes.  Class decides.

2. 35% Portfolio

3. 35% Team Project

4. 10% Participation



          Each student will build a primary literature portfolio, finding, on average, 1 good/substantial research paper/week to add to their portfolio.  You should find a paper appropo to each week’s class topic.

          The final portfolio must contain 10 papers

          Each paper must be printed out or available on CD as a .pdf file.

          Each paper must be accompanied with 1-3 page single-spaced synopsis, printed out or on CD as a .pdf or .doc file.

           The synopsis must contain:

                    — the purpose of the work and the key questions

                    list of key outcomes of the research

                    — 1-2 key figures annotated (important aspects of figures, not just repeat of

                              legends); be numeric when you can be.

                  *— outline detail of the discussion;

                               theories, possible interpretations, unresolved questions

                    1-2 cited papers you would definitely want to follow up on and why.


          Team Projects: (link to teams and assignments)

          —Working in pairs, though pairs will change during the course, you will library search and build information about an aspect of environmental plant physiology.  This will become more refined as we proceed.  You will periodically share information with the class so that we all can learn along with you.   Projects will change, but you will gain the information and resources put together by other groups as we proceed (I hope or think!).

          —The final project will be in the form of an annotated PowerPoint presentation in class.  Also the team must turn in electronic copy either on P:\courses\biology\bio245\projects or on CD.

          —Assessment: Along with the electronic copy there must be a summary page stating the process and organization of work that the team used, the contribution of each team member, and acknowledging other team’s contributions.  Each member of the team must sign this statement.


Evaluation of your achievement in this class is based on:

your understanding

your ability to express yourself in a scientific fashion,

your willingness to question results and interpretations,

your ability to integrate various levels of knowledge

your effort to reflect on the material, your participation in discussion, and your congenial and

          enthusiastic attitude.



On plagiarism and academic dishonesty:

Know the Kenyon College rules on academic honesty described in the2004-2005 Course of Study Handbook, pp. 26-29. 

Please understand that citing an author in your text in scientific fashion (see Biol 109 guidelines to writing a paper) does NOT suffice as documentation for quoting directly or essentially paraphrasing the words of another.  In the cases of using words of another or closely paraphrasing, you must use quotes as well as in-text citing.  However, quoting is not favored in science, rather you should make every effort to contextualize in your own words.
