Prerequisites: BISC 101 & 102

DESCRIPTION:

This course is designed to provide an introduction to the world of plants. The course will be divided into two parts. In the first part the major groups of extant plants that comprise the seedless and seed plants will be examined. This part of the course will be covered from an evolutionary perspective, spanning from the first appearance of plants to the major groups present today. Emphasis will be placed on the origin and evolution of the angiosperms and the factors that allowed them to achieve world-wide dominance.

The second part of the course will focus on contemporary angiosperms and will have two themes. The first is the form and function of plants and will cover the organization of the plant body, the shoot and root systems and the different organs, tissues and cells that make up the plant. The origin of the major plant organ and tissue systems, through the activity of the meristems, will be examined as well as the major roles they play during the plant life cycle. This part of the course will establish a sound understanding of the fundamentals of plant biology. The second theme will concentrate on the relationship between humans and plants. Various aspects of human dependence on plants will be examined including agriculture (plants provide us with food), forestry (plants provide wood - a renewable resource) and medicine (plants are a treasure trove of medicinal compounds e.g. taxol a potent anti-cancer drug). This part of the course will place plants in context by demonstrating how they relate to human society.
