==Key Stage 3==
===Meaning===
A '''concentration gradient''' is when one region has a higher [[concentration]] of [[particle]]s than another.
===About Concentration Gradients===
: When there is a '''concentration gradient''' in a [[fluid]] [[particle]]s will [[diffusion|diffuse]] from the higher [[concentration]] to the lower [[concentration]] until there is no longer a '''concentration gradient'''.
==Key Stage 4==
===Meaning===
A '''concentration gradient''' is when one region has a higher [[concentration]] of [[particle]]s than another.
===About Concentration Gradients===
: When there is a '''concentration gradient''' in a [[fluid]] [[particle]]s will [[diffusion|diffuse]] from the higher [[concentration]] to the lower [[concentration]] until there is no longer a '''concentration gradient'''.
: [[Cell (Biology)|Cells]] are able to move [[particle]]s against the '''concentration gradient''' by [[Active Transport|active transport]].
