Question: what is the difference between a leaf and a leaflet?
Answer: A leaflet (occasionally called foliole) in botany is a leaf-like part of a compound leaf. Though it resembles an entire leaf, a leaflet is not borne on a main plant stem or branch, as a leaf is, but rather on a petiole or a branch of the leaf. ... The two main classes of compound leaf morphology are palmate and pinnate.
