directional growth
Growth toward stimulus
Directional growth describes expansion or development along a specific axis or toward a particular point.
In biology, plants exhibit directional growth when stems grow toward light (phototropism) or roots grow downward (gravitropism).
In business and urban planning, directional growth refers to expansion concentrated in one direction: The city's directional growth has been westward for decades.
