Definition
Noun: A simple leaf is a single, undivided leaf blade. Unlike compound leaves, a simple leaf is not separated into distinct leaflets. It may have lobes or teeth along its margin, but these do not reach the central vein (midrib) to form separate units.
Usage
The term is used in botany and plant identification to classify and describe the structure of leaves. * Botanists classify the maple leaf as a simple leaf, even though it has deep lobes. * The key difference is that a simple leaf has a single blade, while a compound leaf is made of multiple leaflets.
