Sycamore trees (Platanus spp.) have alternate leaf arrangement. This means that the leaves are positioned one after the other along the stem, rather than directly across from each other (opposite) or in clusters (whorled). The leaves are typically large and lobed, contributing to the tree's distinctive appearance.
Opposite. Characteristic of maples in general.
The most common is Alternate, the neither most nor least common is the Opposite and The least common is the whorled. By: Eagle R.
Leaves can be classified based on their arrangement on the stem into alternate, opposite, or whorled. In alternate arrangement, leaves are staggered along the stem; in opposite arrangement, they grow in pairs across from each other; and in whorled arrangement, three or more leaves encircle the stem at one point.
3 Kinds of Phyllotaxy are: alternate opposite whorled

A poplar leaf is alternate, meaning it is arranged along the stem in a staggered pattern, with one leaf emerging from each node.

referred to as whorled leaves. This arrangement allows each leaf to receive sufficient sunlight for photosynthesis. Whorled leaves are less common than alternate or opposite leaf arrangements.
Leaves can be arranged on a stem in several ways: alternate, opposite, or whorled. In an alternate arrangement, leaves are positioned singly at different heights along the stem. Opposite leaves grow in pairs directly across from each other, while whorled leaves appear in a circular pattern around the stem at a single node. The arrangement can impact light exposure and photosynthesis efficiency.
In many plants, leaves can be arranged in various patterns, including alternate, opposite, and whorled (radial) arrangements. However, a specific arrangement combining both alternate and opposite leaves is not common in a single plant; typically, a plant will have one of these leaf arrangements consistently. That said, some species may exhibit a whorled pattern at certain growth stages or under specific conditions, where leaves appear in groups around a stem but do not feature both alternate and opposite arrangements simultaneously.
Examples of plants with whorled leaves include members of the Lamiaceae (mint) family such as the peppermint plant (Mentha × piperita) and the common juniper (Juniperus communis) tree. Whorled leaves are characterized by multiple leaves emanating from the same point on the stem in a circular pattern, as opposed to alternate or opposite leaf arrangements.
Leaves can be classified based on their arrangement on the stem (opposite, alternate, whorled), shape (simple, compound), and margin (entire, serrated, lobed).
