    Good practice is to write down what you already know about the essay topic(using memory from the past units) and then go back through the syllabus and add extra information that you missed.

    If you have had the lecture from the chief examiner(or someone representing him) then he will mention 'the 5' which you should always you when writing a plan. For your particular example, here are the 5 sub-topics you should focus on
    Gas exchange and transport
    nutrition and digestion
    movement and co-ordination
    reproduction and growth
    homeostasis and nutrition

    What I do is make bullet pointed notes underneath each of these headings in my plan.

    Hope this helped

    Well, the definition of a species is one that cannot produce fertile offspring with another species. So perhaps you could start with that and build on it a bit and then go on to talk about natural selection and selection pressures and reasons for speciation, such as geographical separation. Obviously that results in a different sequence of DNA and therefore a different appearance and lifestyle. Species develop to fill a particular niche or use a different source of nutrition e.g. birds developing different shaped beaks to eat nuts/fruit/pollen.

    Reproductive isolation :yep:
