Course Description:

The purpose of this course is to introduce students to
the structure and functi
on of plant cell walls

as well as the scientific approaches, methods and techniques used to study plant cell walls
.
Current experimentation and progress in
the plant cell wall field, including practical applications
(e.g., plant
-
based biofuel) will be
disc
ussed and featured in student presentations
.

More
specifically, each student will be assigned a cell wall molecule (e.g., cellulose) and is expected
to: 1
) present a
review
of
that cell wall molecule, including the approaches, methods and
techniques used t
o study that molecule and 2
) p
resent a recent primary research paper on that cell
wall molecule, which is selected in consultation with

the instructor
.

Both
of these
presentations
will be given in front of the entire class within the 2 hour time period. Al
l class members are
expected to read all the selected primary research papers prior to the presentations. Students are
also
expected to provide the instructor with their presentation material
(i.e., PowerPoint’s and/or
other documents)
at least
24 hours

in

advance of their presentation
date
so that
this information

can

b
e posted on the course web page.


Grades will be based on the following:


1.

Attendance

(100 points).


2.

Student review presentation

(100 points).


3
.

Student primary research paper present
ation (100 points).


4
.

Weekly quizzes

(100 points).

Note that failure to provide the presentation material to the instructor 24 hours before assigned
presentation will result in an automatic
4
0 point reduction in the student’s grade.

Thus,
there are
4
