{tag=Microtubule}

There are two families:
* <kinesin> moves in one direction
* <dynein> moves in the other direction

= Eukaryotes can do phatocytosis due to their cytoskeleton
{synonym}

<Power, Sex, Suicide by Nick Lane (2006)> page 53 suggests that one tremendous advantage of <eukaryotes> over <bacteria> is their ability to change shape due to the presence of the <cytoskeleton>, and the lack of a rigid <bacterial cell wall>.

Imagine in a world where there are only <bacteria>, and you can eat entire bacteria in one go, what a huge advantage that is!
