Biology Units 1 – 4

Unit 1 Topics

  • the cell as the structural and functional unit of life
  • cell growth, replacement and death
  • stem cells in differentiation, specialisation and renewal of cells.
  • Plants and animals systems

A student-designed scientific investigation is an essential component of the subject . The investigation involves the generation of primary data and is related to the function and/or the regulation of cells or systems that draws on the key science skills and key knowledge.

Unit 2 Topics

  • relationship between genes, and the environment.
  • analyse patterns of inheritance, interpret pedigree charts and predict outcomes of genetic crosses.
  • reproductive cloning technologies
  • structural, physiological and behavioural adaptations
  • species relationships
  • the contributions of Aboriginal and Torres Strait Islander knowledge and perspectives in understanding the survival of organisms in Australian ecosystems.

A student-directed research investigation into a contemporary ethical issue is an essential component of the subject. The investigation relates to the application of genetic knowledge, reproductive science, inheritance or adaptations and interdependencies beneficial for survival.

Unit 3 Students Explore

  • the relationship between nucleic acids and proteins.
  • the structure and function of gene and expression in prokaryotic and eukaryotic cells.
  •  the biological consequences of manipulating the DNA molecule and applying biotechnologies.
  • the structure, regulation and rate of biochemical pathways, with reference to photosynthesis and cellular respiration.
  • how the application of biotechnologies could lead to improvements in agricultural practices.

Students apply their knowledge of cellular processes through development of the model of the structure of DNA; an exploring issues of genetically modified organisms in agriculture and regulation of gene technologies.

Unit 4 Students Study

  • Different types of pathogens/ disease causing organisms.
  • The human immune system
  • Treatment, vaccination & Challenges of diseases.
  • Evolutionary biology
  • Determining relatedness between species by comparing their structural features and their genes.

Students will analyse case study, data and/or bioethical issues associated with a range of topics ranging from autoimmune diseases; allergic reactions; development of immunotherapy strategies, prevention and eradication of disease; vaccinations; role of selective breeding programs in conservation of endangered species; or impact of new technologies on the study of evolutionary biology.

A student-designed scientific investigation involving the generation of primary data related to cellular processes and/or how life changes and responds to challenges is undertaken in the course.
