Leaf Shapes Quiz – Shapes With a Purpose
Leaves come in a remarkable range of shapes, from slender pine needles to the giant floating pads of Victoria amazonica. Botanists describe leaves by their shape, edges, veins and how they are arranged on the stem.
Simple leaves have one blade, like oak and maple, while compound leaves are split into leaflets, like ash and walnut. Edges may be smooth, toothed or lobed, and veins form nets in most broadleaf plants but run in parallel lines in grasses and lilies.
Leaf shape reflects how plants live. Shade plants grow broad leaves to catch scarce light, desert plants have small or waxy leaves to save water and conifers use needles to survive cold and snow. Leaf shapes are also key clues for identifying trees.
