· Lab projects, drawings or exams submitted or taken late will be worth 10% less each day delayed (including weekends). Drawings are due one week after assignment.

· Lecture exams are short answer and essay. Lab exams include identification of structures and demonstration of skills (e.g. ability to find archegonia on live material).

· Students are encouraged to work together in the laboratory and compare lab project results, however each student must submit lab projects and drawings independently for assessment.

·Additional readings will be assigned for discussion. These readings will serve to introduce concepts not covered in the textbook.

●Each student will lead a discussion. Participation in discussions and lab projects is essential. Degree of participation (engagement in discussion, preparation, questions, etc.) will determine the participation grade. Through the readings and class materials, you should be able to formulate your own thoughts on the topics discussed and verbally defend your ideas. Be prepared to express your thoughts, listen to others and discuss the issues.

Course Description

The course is designed to give you a broad overview of plant diversity and biology with emphasis on structure and function of plants (extinct and extant). Students will learn to recognize the different groups of plants and understand the distinctions between groups. We will examine the form and function of plants in the context of evolution and ecology in order to understand why particular structures exist. Overall, the course should provide you with a background to understand and appreciate the diversity of plants.
