Year 11 Biology students are looking forward to their excursion to Melbourne Zoo in a couple of weeks. As part of our study of Adaptations of organisms – including structural, functional and behavioural adaptations and reproductive strategies of organisms, we will be spending the day in Melbourne.
This Thursday we are looking at Chapter 7; Activity 7.3 in your practical manual – Human Reproduction. We will be labelling diagrams of the male and female reproductive systems and watching a short video.
Reproduction in other animals, including oviporous, viviporous and ovovivaporous animals.
The Reproductive systems of males and females, including labelled diagrams.
Role of hormones in human reproduction.

The life cycle of a fern is beautiful and a little complex, but can be learnt with the aid of diagrams. The fern has two life stages – a tiny, haploid phase (the gametophyte – n) and a diploid phase (the sporophyte – 2n), which is the obvious and recognisable plant.

This week we are looking at reproduction – by the end of this unit you will understand the concepts of sexual and asexual reproduction and describe how reproduction occurs in unicellular and multicellular organisms. You will learn that prokaryotes reproduce by binary fission and that eukaryotes can also reproduce asexually by mitosis, budding, parthenogenesis or vegetative reproduction (runners, rhizomes, tubers, bulbs and cuttings). More about asexual reproduction here. PowerPoint about Asexual Reproduction at SlideShare. Introduction to Reproduction and asexual reproduction at About Biology.
Sexual reproduction occurs in both plants and animals and involves the production of gametes by meiosis. Fertilization (when male and female gametes meet) can be external, as in many marine and freshwater organisms, or internal, as in most terrestrial vertebrates, such as birds, reptiles and mammals.
