AWhorled
BSessile
CCompound
DPalmate
Answer & Solution
Correct answer: B. Sessile
1. Many leaves join the stem through a stalk called the petiole.
2. Leaves with no petiole, attached directly to the stem, are sessile.
3. Whorled describes an arrangement of three or more leaves at one node, which is a different property.
4. Compound and palmate describe how the blade is divided rather than how the leaf attaches.
