Types of Compound Leaves — NEET Biology

Which of the following statements regarding leaf structure and types are correct? S1: A leaf is considered simple if its lamina is entire or if, when incised, the incisions do not touch the midrib. S2: In a pinnately compound leaf, a number of leaflets are present on a common axis called the rachis, as seen in silk cotton. S3: Palmately compound leaves have leaflets attached at a common point, i.e., at the tip of the petiole, for example, neem. S4: A bud is present in the axil of the petiole in both simple and compound leaves, but never in the axil of leaflets of a compound leaf. S5: Leaves are lateral, generally flattened structures borne on the stem, originating from shoot apical meristems and arranged in an acropetal order.
