Which of the following species has an alternate leaf arrangement?

Buckeye, Horsechestnut
Acer
Oaks
Magnolia

The correct answer is: Acer

The correct answer is Acer, which includes species like maples. In botany, an alternate leaf arrangement refers to the pattern where leaves are staggered along the stem, with one leaf per node, resulting in a more dispersed appearance. Acer species typically exhibit this alternating pattern, which helps maximize sunlight exposure and reduces overlap with other leaves, promoting photosynthesis. In contrast, the other species mentioned typically exhibit different leaf arrangements. Horsechestnut and buckeye typically have opposite leaf arrangements, as do many oaks, while magnolia generally has a whorled or spiral leaf arrangement. Recognizing these patterns is crucial for proper tree identification and understanding their growth habits.
