In this video, we look at the structure and function of centrioles, cilia and flagella. First we look at centrioles and their roles in eukaryotic cells including the assembly of spindle fibres during cell division. We then look at the role of centrioles in cilia and flagella.

This video is aimed at the UK A Level Biology specifications. Students studying International A Level Biology will need to check their specification.
