===Function===
: A '''flagellum''' allows a [[Cell (Biology)|cell]] to move towards food and away from danger.
===About Flagella===
: [[Cell (Biology)|Cells]] can have more than one '''flagella'''.
: The '''flagellum''' is sensitive to certain [[chemical]]s and to [[temperature]] and will begin moving when certain [[chemical]]s and [[temperature]]s are detected.

==Key Stage 4==
===Meaning===
A '''flagellum''' is a tail like [[organelle]] found on [[bacteria]] and some [[protist]]s used to help it move.
===Function===
: A '''flagellum''' allows a [[Cell (Biology)|cell]] to move towards food and away from harsh [[environment]]al conditions.
===About Flagella===
: [[Cell (Biology)|Cells]] can have more than one '''flagella'''.
: '''Flagella''' are found on some [[bacteria]] such as [[Escherichia coli|E.coli]] and on some [[protist]]s such as [[euglena]].
: The '''flagellum''' is sensitive to certain [[chemical]]s and to [[temperature]] and will begin moving when certain [[chemical]]s and [[temperature]]s are detected.
===Examples===
{| class="wikitable"
