Introductory Life Sciences

BIOL 1000 Introductory Life Sciences (ILS)

Introductory Life Sciences I (ILS) (this course is restricted to 500 students), the "core" course that gives entry to all subjects in the Biological Sciences in second year, conprises four topics, 1 topic per teaching block. Introductory Life Sciences I will be offered on two slots to allow for maximum flexibility. To be credited with Introductory Life Sciences 1 (36 points) you must complete all four topics.

Introductory Molecualr and Cellular Biology

The underlying theme of the knowledge base will be the relationship between structure and function at the molecular and cellular levels. After attending this topic, students should be able to justify why the cell can be considered the basic unit of life and explain how structure determines function in the cell. To this end, the structure of biomolecules and their roles in the cell will be examined, as well as how cells capture and use energy.

Growth and Development

This topic will start with a study of the cell cycle (including cytokinesis and the reproduction of cells) and the flow of genetic information in the cell. The processes underlying cell growth, morphogenesis and differentiation in the development of living organisms will be explored and the principles of evolution will be examined.

Structure and Function

The objective of this topic will be to explain the relationship between structure and function using homeostatis as a common theme linking anatomy, physiology and evolution. Students will become familiar with the relevant vocabulary and important principles involved and will have improved skills in observing structure and interpreting experiments. NB: Dissection of the rat is a compulsory component of this course. Failure to complete dissections could result in your DP requirement not being met. 

Ecology and Diversty

The Diversity component introduces students to the spectacular range of plants and animals. The section on ecology and environmental issues covers ecological theory, knowledge of field practice, knowledge of southern African ecosystems and environmental problems, knowledge of the environment of organisms (habitat, soil, water, radiation), examples of application of theory to environmental issues.
