Objectives The objective of this subject is to introduce to first-year students the basic and general concepts underlying the structure and function of cells, tissues and organisms. This generalised background is essential so that students, many of whom have not undertaken VCE biology, will have a good foundation in biology to undertake specialised subjects later in the degree. This subject is designed to provide an understanding of the key concepts in structure, function and evolution of single cells and how microbes impact on human health. Students will then learn how single cells specialise and aggregate to form different tissue types and how such tissues form functional systems which enable whole organisms to survive and reproduce. In addition to the basic theoretical knowledge, students will learn how modern tools and histological techniques are used to study single cells and tissues. Apart from specific subject-based knowledge, students will also be introduced to specific skills such as essay and report writing, oral presentations and problem solving activities. Students completing this subject will have a solid foundation in basic biology so that they can undertake a variety of subjects and electives as part of their Bachelor of Biomedical Science degree.

Synopsis The chemical constituents of living cells and biological reactions. Cell structure and function including cells as basic building blocks, common characteristics of all cells, prokaryotes and eukaryotes, membranes, organelles and evolutionary origin of cells. Animal diversity and evolution including origin of life, major invertebrate phyla, origin of vertebrates and vertebrate classes. Functional systems including respiratory gas exchange, circulatory system, osmoregulation and excretion, thermoregulation, nervous system. The relevance of the microbial world in biomedical science including the six kingdoms, prokaryotes and eukaryotes, microscopic examination of bacterial cells, bacterial growth and virus infection cycle. Tools for studying cells including histology, different types of microscopy, tissue culture and specialised cell staining techniques.
