AThe petiole
BThe axillary bud
CThe apical bud
DThe internode
Answer & Solution
Correct answer: D. The internode
1. Nodes are the points where leaves, aerial roots and flowers attach to a stem.
2. The stretch of stem between two nodes is the internode.
3. A petiole is the stalk running from the stem to the base of the leaf, so it is not a stem region.
4. An axillary bud sits in the axil between leaf base and stem, and the apical bud sits at the shoot tip.
