AGRO/HORT 100G -- Introduction to Plant Science
Fall 2003/ MWF 12:30-1:20 GT 337
Instructor: Carol Potenza, PhD
[email protected]
Office Hours:
Monday: 1:30-12:20, Tues. 8:30-9:30; Skeen Hall N333
Textbooks: Introductory Plant Biology, K. Stern 9th Ed. 2003
Introduction to Horticulture and Agronomy: Lab Manual, K. Lombard, A. Wagner, J.
Mexal, R. Mostafavi (available in Ag Communications office GTH173) –Dr Chris Cramer will be
overseeing the lab. Lab will start the first week of class.
Supplemental information is provided in the class.
Course Objective: To teach students the scientific method as it is applied in the discipline
of plant science. At the end of the course students will have learned the basic chemical, physical
and biological principles that govern plant growth in different environments and be able to design
experiments to test hypotheses based on these principles.
Catalog Description: Lecture and laboratory. Introductory course presenting the physical,
biological, and chemical principles underlying plant growth and development in managed
ecosystems. In the laboratory portion of the class, students perform experiments demonstrating
the principles covered in lecture. The course uses economic plants and agriculturally relevant
ecosystems to demonstrate basic principles. Appropriate for non-science majors.

Grading: The final grade for this course will be based on 1000 points. Students should note that only ~40%
of the grade is based on tests, 30% of the grade is based a paper, an oral presentation and homework, and
30% of the grade is based on lab reports and lab attendance, reflecting the importance of the
laboratory portion of this course. Attendance at lab is mandatory.

You will be expected to keep track of your points and grade throughout the semester. You can email me for
periodic updates and point comparisons.
Quizzes will take up the last 20-25 minutes of class time and can cover anything presented in lecture or in the
assigned text chapters and will not include the lecture presented on quiz days. Students may make up missed
quizzes if taken before the next scheduled class period. Homework is worth 25 points per assignment. You
are encouraged to study and work with others, but not copy others’ answers. Homework with identical
answers will get zero points for those questions. Late homework will be accepted but will suffer a penalty
(Loss of a whole grade per day late, starting 10 minutes after start of class on the due date). Letter grades will
be assigned as follows: A >900 points; B 800-899 points; C 700-799 points; D 600-699 points; F < 600
points.

Writing assignments:
There are several different types of writing assignments in this class: an essay; short essay questions in
homework problem sets and final exam, and lab reports.
The essay assignment is really a two-part assignment, a written presentation worth 100 points and an
oral presentation of the written report and a defense of the conclusions of the essay worth 50
points. You MUST submit a written report to participate in the oral debate.
Essay assignmentPlease give an educated overview and select one of the crops (a-d) to
research historically and as a genetically modified crop in production now. Include
pros/cons and conclude with your specific opinion on GMOs as a separate final paragraph.
Essay TopicGenetically modified organisms (GMOs) in agriculture:
(choose one of the listed crops to research)
•corn/maize
•rice
•soybeans
•papaya
You will select which of the crops you wish to research and sign-up on September 5th. The written
portion of the assignment is due Friday November 14, 2003. There are to be at least 8 well-cited
references from 1996-2003. These may include up to four web references. The document is to be
typed and at least 4 pages double-spaced and no more than 10 pages. The oral presentations will be
on November 19, on November 21 and on November 23. I will select which students present
on which days.

Grading Policies: Any missed assignments/quizzes/papers will receive zero points without a valid
excuse given BEFORE you miss the assignment. I will make rare exceptions for specific hardships as
long as you have validated notes or letters from doctors/faculty advisors etc. Valid/invalid excuses will
be determined at the discretion of the instructors or your lab T.A.
Academic misconduct/Plagiarism: Please read the NMSU Student Handbook, especially the
sections pertaining to academic misconduct, as they will strictly apply in this course. Additional
comments about plagiarism: Plagiarism includes copying sentences or paragraphs from a scientific
paper/references/fellow students when writing a report. This means that students must use their own
words. Any information gathered from an outside source must be referenced and stated in your own
words. Reports will be checked for acts of plagiarism. A single plagiarized sentence will result in a zero
for that assignment. The instructors will strongly enforce these rules.
Students with Disabilities: If you have or believe you have a disability, you may wish to selfidentify. You can do so by providing documentation to the office for Services for Students with
Disabilities, located at Garcia Annex (646-6840). Appropriate accommodations may then be provided for
you.
If you have a condition which may affect your ability to exit safely from the premises in an
emergency, or which may cause an emergency during class, you are encouraged to discuss this in
confidence with the instructor and/or the director of Disable Student Programs. If you have general
questions about the Americans with Disabilities Act (ADA), call 646-3333.

How Important are plants to life as we
know it?
•Plant life constitutes over 98% of the total biomass on earth
(Biomass in the total dry weight of living
organisms)
*Plants/ “green” organisms have the EXCLUSIVE ability to
produce oxygen
*Plants remove large amounts of carbon dioxide given off
by all living organisms

For example…
A Lower-Emission Leonardo DiCaprio. By Tom Cunneff.
Leonardo DiCaprio is now "carbon neutral." Working with an
environmental group called Future Forests, the eco-friendly actor is
helping offset global carbon emissions (which exacerbate the
greenhouse effect) by sponsoring the planting of 1,000 trees.
Actually, according to Future Forests, it only takes 15 trees to
"neutralize" DiCaprio, whose carbon dioxide emissions are about half
of an average American's since he drives an electric car.

Human and Animal Dependence on Plants
•
Plants are the source of multiple products of
human society:
 Food
 Perfumes
 Dyes
 Beverages
 Lumber
 Paper
 Clothing

Botany As A Science
•
•
At first, interest in plants was practical.
 Centered around the production of food,
fibers, fuel, and medicine.
Eventually, an intellectual interest arose.
 Science involves the observation,
recording, organization, and classification
of information.

Scientific Method
•
•
•
Hypothesis - Tentative, unproven explanation
of an observation.
Experiment - Test to determine if a
hypothesis is correct.
 Variables - Aspects of the experiment that
can be changed or held constant.
- Control - All variables held constant.
Data - Results from the experiment.

•
•
Genetics
 Science of Heredity
- Enormous potential for further
development of better agricultural,
