Which leaf arrangement features leaves in opposite pairs at the node?

• A. Alternate leaf
• B. Whorled leaf
• C. Opposite leaf
• D. Simple leaf

Answer: (C)

Leaf arrangement describes how leaves attach to the stem. In opposite arrangement, leaves appear in pairs at the same node on opposite sides of the stem. This pairing creates a mirrored pattern as you move upward. It differs from an alternate pattern, where only one leaf sits at each node and the leaves alternate sides as you go up the stem, and from a whorled pattern, where three or more leaves share a single node around the stem. Simple leaf refers to the leaf blade being a single, undivided unit, not to how leaves are arranged on the stem.
