Which leaf arrangement describes one leaf at each node along the stem?

• A. Alternate (leaf arrangement)
• B. Opposite
• C. Whorled
• D. Rosette

Answer: (A)

Leaf arrangement along the stem is about how many leaves attach at each node and where they sit as the plant grows. When there is one leaf at each node, the leaves appear on alternating sides along the stem, creating a staggered or zigzag pattern. This description precisely matches the alternating arrangement: a single leaf per node along the stem. Two leaves per node on opposite sides describe the opposite arrangement, while three or more leaves at a node describe a whorled pattern. A rosette is a cluster of leaves at the base rather than along the stem. So the single-leaf-per-node pattern is the best fit for “one leaf at each node along the stem.”
