Protist Motility
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Protists move by flagella, which they whip or rotate; by cilia, beaten in coordinated waves; or by pseudopodia, extensions anchored and pulled forward.
Show
Paramecium swims by coordinated ciliary beating, while an amoeba extends a pseudopod, anchors it, then pulls its cytoplasm forward.
Watch for
These three motility types are not exclusive across protists — some lineages use more than one at different life stages.
