Sample course outline
Biology – General Year 12
Unit 3 and Unit 4
Semester 1 – Unit 3 – Reproduction and inheritance
Key teaching points
Asexual reproduction
 asexual reproduction (binary fission, budding, vegetative propagation, cuttings, bulbs, tubers,
spores, parthenogenesis)
 plant propagation by asexual reproduction
 observation of yeast cells
 use of the microscope
Cell division
 mitosis
 use of the microscope to observe growing root cells
 meiosis
Sexual reproduction
 types of gametes
 fertilisation (restoring the diploid number)
Life cycle of a flowering plant
 alternation of haploid and diploid stages
Reproduction in flowering plants
 structure and function of parts of the flower
 dissection of a variety of flowers (real or virtual dissections)
 mechanisms of pollination
 human facilitation in pollination of native plants
 seed dispersal – agents for dispersal and adaptations, self-dispersal mechanisms
 adaptations of Australian plants to regular burning – seed dispersal and recolonisation
 requirements for germination
 use of smoke-water to promote germination in native Australian plants
Task 1: Science inquiry – Reproduction in flowering plants
Animal reproduction
 reproductive structures for external and internal fertilisation
 timing of reproduction
 strategies for survival of offspring, including parental care and number of offspring
Life cycles of animals
 life cycle of insects/amphibians and Australian marsupials
 pest control based on knowledge of life cycles
Task 2: Test – Reproduction
