Content:

This course is designed to provide a unified view of the form and function of living organisms. Rooted in comparative physiology and functional morphology, it relates the laws of physics and chemistry to the fundamental processes of living organisms. These processes include the acquisition, distribution, storage, and allocation of energy and materials, and the mechanisms involved in growth, development, reproduction, and communication. The focus is on the integrated functioning of the whole organism and its component organ systems. Implications for population, community and ecosystem processes are discussed. Examples are drawn from a wide range of organisms, but the emphasis is on higher plants and vertebrate animals. The course assumes a background in basic biology, chemistry and physics.

Readings:
Only the Course Pack is required.
Method:
Three lectures per week, and optional conference sessions for review and clarification of course material.
Evaluation:

Four open-book quizzes consisting of conceptual (applying knowledge to novel scenarios) multiple choice questions. Two of the quizzes are in-class promoting discussion and peer-to-peer learning.
Two midterm examinations and a final exam of multiple choice and short answer questions
