Principles of Biology I (Biology-202) Lecture


Life reveals itself in millions of distinct species, ranging from unicellular prokaryotes like the common gut bacterium Escherichia coli to highly complex multicellular eukaryotes like ourselves. As fascinating as this diversity of life is, the underlying unity of life, which shows, for example, in the use of common building materials and the same fundamental processes in such diverse species as E. coli and human beings, is equally impressive. In "Principles of Biology I" we will discuss mainly this Unity of Life.
We will begin our study of life with a look at the "Organization of Life", at the molecular and the cellular level. The following discussion of the "Energy Transfer through Living Systems" will show how most cells release energy during respiration to maintain their structural and functional integrity, and how plant cells bring this energy into the living world by capturing sunlight during photosynthesis. We will then study the two key aspects of the remarkable "Continuity of Life": the hereditary processes, which guarantee continuity of characteristic features between generations of individuals, and the principles of evolution, which ensure continuity of living beings through adaptation.

Neil A. Campbell and Jane B. Reece
BIOLOGY, 7th edition

Benjamin Cummings, 2005

Packaged with the book, you will receive the interactive CD-ROM "Student Media for Biology, 7th ed." I highly recommend using this CD. Important concepts in biology will become clearer, when you see them in animations and when you can manipulate parameters in interactive exercises.

In addition, the publisher maintains a book-specific website. Here you will find learning resources such as practice quizzes, a glossary, and other useful tools.


Exams and Grading

Three midterm exams, a final exam (all PowerPoint multiple choice), one 30-minute lab practical and one lab report. In addition, your attendance and participation in the lab will be evaluated.
