Course Description
This laboratory course is designed to introduce you to a variety of topics and methods within the field of plant biology. Topics will include the cell, tissue, and organ structure of vascular seed plants, molecular taxonomy, and experimental investigation of selected plant processes such as photosynthesis, transpiration, and hormonal interactions in growth and development. We will use a variety of techniques and approaches in our studies, including microscopy, physiological techniques, and molecular biology. In addition, you will carry out a semester-long independent analysis of an unknown plant.Course requirements
You are responsible for your own safety during laboratory classes. The most important safety rule is to think before acting. Wear protective devices whenever needed including eye protection, lab coats, and gloves. If you have a question about a safety issue, stop the experiment and ask.
Laboratory practice
You are responsible for the equipment and space that you use - please leave the equipment and laboratory/plant growth spaces in the same (or better!) condition than you found them. Clean all glassware, potting supplies, benchtops, and instruments thoroughly.
Grading scheme/assignments
oral presentation 10%
written lab report 15%
effort and approach 10%
Late penalties
A 10% penalty per day will be exacted for any written assignment turned in late. Oral presentations may be given on the assigned date only (no late presentations will be accepted).Academic honesty
I strongly encourage you to exchange information, discuss class material, and bounce ideas off of one another (and me). However, all work submitted for evaluation must be your own, and all contributions from others must be explicitly acknowledged (state who you worked with and the nature of the interaction). Please review the College policy on academic honesty. If you have questions or are unsure, please ask!Disabilities
If you have a physical, psychological, medical or learning disability that may impact your ability to participate fully in this class, I would urge that you contact the Office of Disability Services at 5453. The Coordinator of Disability Services, Erin Salva (salvae@kenyon.edu), will review your concerns and determine, with you, what accommodations are appropriate. All information and documentation of disability is confidential. In addition, please feel free to discuss your concerns with me in private.Lab schedule
