Biology
Annual rings are the number of :
- Internodes in a stem
- Rings of vascular bundles in a monocot stem.
- Bark layers in a woody stem.
- Layers of Xylem in a stem.
Answer
Layers of Xylem in a stem.
Reason— Older xylem forms wood and does not take part in transport. The annual rings seen in woody stems are formed due to successive layers of xylem.
Internodes are segments between two nodes. Monocot stems have scattered vascular bundles, not rings. Bark is the outer protective covering of stems. It does not form annual rings.
