Detailed explanation-1: -In compound leaves, a blade has two or more subunits called leaflets: in palmately compound leaves, the leaflets radiate from a single point at the distal end of the petiole; in pinnately compound leaves, a row of leaflets forms on either side of an extension of…

Detailed explanation-2: -Pinnation means the formation of leaflets by dividing a leaf.

Detailed explanation-3: -Compound: The leaf is separated into distinct leaflets, each with its own small petiole (but without an axillary bud). Simple: The leaf may be lobed or divided, but does not form distinct leaflets.

Detailed explanation-4: -In a compound leaf, the leaf blade is completely divided, forming leaflets, as in the locust tree. Compound leaves are a characteristic of some families of higher plants.

Detailed explanation-5: -To distinguish a leaf from a leaflet, simple and compound leaves have a bud at their base, but a leaflet does not. For compound leaf searches it is possible to search by the entire leaf shape or a search can be made by the individual leaflet shape.
