Definition
'Abaxial' describes the surface of a plant part that faces away from the axis or stem. It's often referred to as the lower surface of a leaf. Think of it as the 'back' of a leaf, the side you usually don't see as much. Unlike 'adaxial,' which is the upper surface, 'abaxial' is oriented away from the central stem. In simple terms, if a leaf were a face, the abaxial side would be the chin. ðŋ
