Examples

Such stress "tolerators" may be particularly indicative of adaptive relationships between leaf form and function (Fahn and Cutler 1992, Levitt 1980).

Academic text (1997)
In this article, we present a synthesis of current findings in ecology, physiology, and biochemistry that points to a fundamental relationship between the evolution of leaf form (structure and orientation) and photosynthetic performance.

Academic text (1997)
Yet, only recently has any functional relationship between leaf form and photosynthetic performance been suggested.

Academic text (1997)
Plants that produce these divergent leaf forms may have greater fitness than an individual able to produce only one type or the other.

Academic text (2000)
Himalayan tree species display a variety of leaf forms and represent major families from both tropical and temperate regions.

Academic text (1997)
It seems logical that leaf form would have evolved to maximize photosynthesis per unit leaf biomass in the face of these opposing internal gradients of light and carbon dioxide.

Academic text (1997)
Future studies that attempt to explain the relationships between leaf form and function, as related to photosynthetic performance, should be directed toward identifying the mechanisms that control light and carbon dioxide gradients inside leaves, as well as the corresponding effects of these mechanisms on whole-leaf photosynthesis (Figure 3).

Academic text (1997)
Scientists study different leaf forms to understand how they adapt to various environmental conditions.
The oak tree is known for its distinctive leaf form, which sets it apart from other tree species.

Morphology

leaf + form

The meaning is directly and transparently derived from combining 'leaf' (a plant organ) with 'form' (shape or appearance) to denote the shape of a leaf. This noun+noun compositional pattern is straightforward and cross-linguistically common, so a B1 learner who knows both constituents should be able to infer the meaning.

Etymology

Leaf form The noun leaf form simply describes the visible shape of a plant's leaf, and the word form here means 'shape'. Early plant watchers grouped plants by these clear shapes, such as heart-shaped, needle-like or compound leaves, so leaf form came to mean the shapes used to 'identify' and 'classify' plants.
