Which venation pattern is described for maples?

Explanation:
Maple leaves show palmate venation, where several main veins originate from a single point at the leaf base and spread out toward the edges. This radiating pattern is what makes maples distinctive, with multiple primary veins like spokes from the base. Pinnate venation would have one central midrib with side veins along its length, which isn’t how maples are structured. Dichotomous venation involves veins that repeatedly fork into two, a pattern seen in some ferns, not maples. Parallel venation has veins running side by side from base to tip, typical of many grasses, not maples.
