 * Starter**

This topic can be done by self-study to a large degree. If this approach is taken it is recommended that you:
 * Approach**
 * 1) download the presentation (so the animations and narrations work)
 * 2) go through the workbook and watch the videos in the appropraite places
 * 3) download the workbook and attempt it with any resources to check how you have learn and retained
 * 4) complete the workbook using the presentation and videos to help yourself
 * 5) ask for the markscheme and exchange workbooks with a friend and mark and annotate improvements on each others work using the markscheme as guidance

These are the skills and content you should be able to master by the end of this topic
 * Outcomes **

General (animals and plants) 3.1 describe the differences between sexual and asexual reproduction 3.2 understand that fertilisation involves the fusion of a male and female gamete to produce a zygote that undergoes cell division and develops into an embryo

Flowering plants 3.3 describe the structures of an insect-pollinated and a wind-pollinated flower and explain how each is adapted for pollination 3.4 understand that the growth of the pollen tube followed by fertilisation leads to seed and fruit formation 3.5 understand the conditions needed for seed germination 3.6 understand how germinating seeds utilise food reserves until the seedling can carry out photosynthesis 3.7 understand that plants can reproduce asexually by natural methods (illustrated by runners) and by artificial methods (illustrated by cuttings)

 * Workbook and notes **

The main supporting presentation for the workbook (again a great resource from [|Clickbiology]) It's large and contains embedded video links you may find the embedded version below easier to use, but beware the audio narrations and the animations won't work until it's downloaded. Alternate links to the videos can be found underneath. media type="custom" key="27835829"

A diagram from of an insect pollinated flower from [|SAPS] This good [|simple tutorial from BBC Bitesize] covers the basics about plant reproduction, this link is to flower structure, but you can find information on all the different aspects [|Tutorial on flower structure] from JBS (check your objectives and workbook - you don't need to know all the details given in the tutorial)
 * Other resources**

Explore flower structure by dissection of a large insect pollinated plant such as a star-gazer lily. Pollen grains can be observed under a microscope following the dissection. Dissection is ideally done before the self-study workbook and presentation, but after en introduction, e.g. a video.
 * Suggested activities **

Germination experiment - setup a simple germination experiment to support the learning of 3.5 conditions needed for germination. Mung bean seeds can be placed in comparative conditions to easily assess the affect of light vs. darkness, temperature and water. Extension: students select a particular condition and design an extended investigation to examine it's importance in detail.
