4 | Evolution of Australian biota

3: Continuation of species has resulted, in part, from the reproductive adaptations that have evolved in Australian plants and animals

Lesson 1 | Meiosis vs mitosis

  • Distinguish between the processes of meiosis and mitosis in terms of the daughter cells produced

  • Analyse information from secondary sources to tabulate the differences that distinguish the processes of mitosis and meiosis

Lesson 2 | Fertilisation in animals

  • Compare and contrast external and internal fertilisation

  • Discuss the relative success of these forms of fertilisation in relation to the colonisation of terrestrial and aquatic environments

  • Identify data sources, gather, process and analyse information from secondary sources and use available evidence to discuss the relative success of internal and external fertilisation in relation to the colonisation of terrestrial and aquatic environments

Lesson 3 | Australian flora

  • Describe some mechanisms found in Australian flora for :
    – Pollination
    – Seed dispersal
    – Asexual reproduction with reference to local examples

  • Explain how the evolution of these reproductive adaptations has increased the chances of continuity of the species in the Australian environment

  • Describe the conditions under which asexual reproduction is advantageous, with reference to specific Australian examples

Lesson 4 | Flowers

  • Plan, choose equipment or resources and perform a first-hand investigation to gather and present information about flowers of native species of angiosperms to identify features that may be adaptations for wind and insect/bird/mammal pollination

Lesson 5 | Australian fauna

  • Describe some mechanisms found in Australian fauna to ensure:
    – Fertilisation
    – Survival of the embryo and of the young after birth

  • Explain how the evolution of these reproductive adaptations has increased the chances of continuity of the species in the Australian environment

  • Describe the conditions under which asexual reproduction is advantageous, with reference to specific Australian examples
