This resource is most likely to be used as an extension activity for gifted & talented or high ability pupils in GCSE, A-level or IB biology. Both the student sheet and answers (separate teacher sheet) are provided for download. The activity provides a detailed diagram showing the process of fertilisation in mammals, which pupils are expected to label and annotate. Pupils will be required to recognise the function of the acrosome in sperm and the cortical reaction, which prevents polyspermy.

Great resource. Clear worksheet and very visual layout. Not rated 5 stars as I would have preferred more questions/exercises/worksheets for the price (£2.50).
