BIOL S205 is systematically organized into a total of five study units. Each study unit begins with an introduction that outlines the principle focus of the subject area. This is followed by a list of learning outcomes so that you are aware of what you are expected to accomplish through the completion of the study unit. The study unit is broken down into a number of topics. In each topic, key concepts will be presented through readings from the textbook, multimedia demonstrations, activities and self-tests. In order to pursue a systematic approach to learning, you are recommended to do the following:
- Read through the set of learning outcomes listed for each unit.
- Study the key concepts presented for each topic area.
- Work through the assigned readings and online resources stated in the units.
- Attempt the unit activities and self-tests questions and check the feedback at the end of the units.
- Get the assignments (assignments or laboratory reports) to your tutor on time.
In addition to the study units, course content will be delivered through two compulsory face-to-face day schools, which are an integral part of the course.
Course materials
A brief description of each study unit is given below.
Unit 1 The biological molecules of life
Given the rich complexity of life on Earth, we might expect organisms to have an enormous diversity of molecules. Remarkably, the critically important large molecules of all living things fall into just four main classes: carbohydrates, lipids, proteins and nucleic acids. Unit 1 focuses mainly on the architecture of these biological macromolecules and explores how such a small group of macromolecules can contribute towards a diverse array of cellular functions that occur within living organisms.
Unit 2 Composition of the cell
In the hierarchy of biological organization, the cell is the smallest collection of matter that can live and survive. Although cells differ structurally from one another according to their differential functions, they share certain common characteristics. Unit 2 inspects the subcellular details of a typical cell and examines how cooperation of these subcellular components can regulate intracellular functions. In addition, structure and function of the extracellular components such as the plant cell wall as well as intercellular junctions will be reviewed and emphasized.
Unit 3 The energy of life
Chemical elements essential to life are recycled. Photosynthesis generates oxygen and organic molecules used by mitochondria of eukaryotes as fuel for cellular respiration. Respiration breaks the fuel down to generate ATP and releases carbon dioxide and water as waste products. With the recycling process coupled between cellular respiration and photosynthesis, the focus of Unit 3 is to compare and contrast cellular respiration and photosynthesis. Moreover, other alternate pathways will be reviewed and commented.
Unit 4 Cell cycle and genetics
The ability of organisms to reproduce their own kind is the one characteristic that best distinguishes living things from non-living matter. Cell division plays critical roles in the life of organisms in terms of reproduction, growth and repair. Cell division is an integral part of the cell cycle. In Unit 4, different types of cell division will be reviewed. In addition, how sexual life cycles and the Mendelian pattern of inheritance can give rise to genetic diversity will be discussed.
Unit 5 Evolution and generation of diversity
Evolution, originally defined as descent with modification, is a concept that is supported by an overwhelming amount of scientific evidence. The concepts of natural selection, mutation and sexual reproduction have been accepted to be the underlying basis of genetic variation that makes evolution possible. Unit 5 reviews the various mechanisms by which genetic variability is derived. In the latter part of the unit, the basis of uniformity and diversity will be examined and the current phylogenic classification system will be visited.
Set textbook
You are required to purchase the following set textbook:
- Campbell, N A and Reece, J (2015) Biology, 10th edn, San Francisco: Pearson Benjamin Cummings.
Website resources
Throughout the course you will often be required to access the following website:
This website is closely related to your set textbook. An access code to the online resources will be provided when you purchase the book.
In addition, you may find the following recommended online websites useful to refer to during the course, though they are not compulsory:
Face-to-face instruction
Other than the study units, you are required to attend two compulsory day schools planned for the course. The outlines and rationales of these day schools are given below.
Day school 1: Study of membrane permeability in beet root cells
The objective of this day school is to study the functions of phospholipids and proteins in the regulation of movement of molecules across the lipid bilayer of the plasma membrane. Concepts covered in the day school offer an appropriate reinforcement of knowledge to be covered in Unit 2.
Day school 2: Extraction and analysis of chlorophyll pigments by thin-layer chromatography
The objective of this day school is to extract, identify and characterize the various forms of chlorophyll and other accessory photosynthetic pigments that are essential for the process of photosynthesis. Concepts covered in the day school offer an appropriate reinforcement of knowledge to be covered in Unit 3.
