Leaves arranged singly along the stem, one leaf per node are called?

• A. Alternate Leaves
• B. Opposite Leaves
• C. Whorled Leaves
• D. Rosette

Answer: (A)

Leaf arrangement along the stem, or phyllotaxy, shows how leaves attach at each node. When there is one leaf arising at each node, and these leaves appear on alternating sides as you go up the stem, the pattern is called alternate leaves. This single-leaf-per-node arrangement contrasts with opposite leaves, where two leaves emerge opposite each other at the same node; whorled leaves, where three or more leaves come from the same node; and a rosette, which is a cluster of leaves at the base rather than along the stem. Knowing this helps with identifying plants and understanding how the plant grows and interacts with light in a turf setting.
