A leaflet is defined as a leaf-like part or blade of a compound leaf. In botany, a compound leaf is one that consists of multiple leaflets attached to a single stem, known as a petiole. Each leaflet resembles a simple leaf, but it is part of a larger structure.

The distinction between leaflets and simple leaves is important because leaflets do not have buds at their base, which differentiates them from the primary leaves of a plant. Understanding this concept is crucial when studying plant anatomy and identifying different types of foliage.

In contrast, the other choices do not accurately reflect the definition of a leaflet. For instance, a small flower that grows on a leaf is not related to the structure of leaflets, while a type of tree producing strong wood does not pertain to the characteristics of leaves. Additionally, a stem that connects leaves to a branch describes a petiole rather than a leaflet. Each of these incorrect options fails to capture the botanical classification and function of leaflets.
