See it on the paper →Comprehensive responses • Many candidates could describe the adaptive features of sperm including flagellum, mitochondria, enzymes in acrosome and a haploid nucleus. Limited responses • Fewer candidates explained the adaptive features of sperm. • Some candidates stated that flagellum help the sperm to swim and did not include that sperm swim to meet the egg. • Some candidates stated that the acro...

The function of the flagellum was the most well known and for many this was their only correct response. Whilst many appreciated that the function of mitochondria involves energy, many incorrectly discussed making or creating energy or termed them the powerhouse of the cell. Acrosome was the least well known. Common non-creditworthy responses included head, sperm, cytoplasm, membrane and cell wall...

Most labelled the flagellum or tail as a feature that adapts sperm for reproduction. Some also identified enzymes, the acrosome or mitochondria. Those labelling the head needed to show that it is the streamlined shape that adapts it for its role. Some candidates just drew label lines with no labels.
