Students:

1. explain the mechanisms of reproduction that ensure the continuity of a species, by analysing sexual and asexual methods of reproduction in a variety of organisms, including but not limited to:

   1. animals: advantages of external and internal fertilisation

   2. plants: asexual and sexual reproduction

   3. fungi: budding, spores

   4. bacteria: binary fission (ACSBL075)

   5. protists: binary fission, budding

2. analyse the features of fertilisation, implantation and hormonal control of pregnancy and birth in mammals (ACSBL075)

3. evaluate the impact of scientific knowledge on the manipulation of plant and animal reproduction in agriculture (ACSBL074)

1.1: Animals: Advantages of external and internal fertilisation

Living things use lots of different strategies for producing offspring, but most strategies fall neatly into the categories of either sexual or asexual reproduction. Asexual reproduction generates offspring that are genetically identical to a single parent. In sexual reproduction, two parents contribute genetic information to produce unique offspring.

Sexual and asexual reproduction have advantages and disadvantages—which is why some organisms do both!

1.2: Plants - Asexual and sexual reproduction

• Most plants have the ability to reproduce both asexually and sexually.

• Think about the factors which may determine whether a plant reproduces sexually or asexually.

• Watch the video below and read the information about sexual v asexual plant reproduction.

1.3 Fungi (budding and spores)

1.4 Bacteria (binary fission)

1.5 Protists: binary fission & budding
