The soft green stems of annuals and biennials (plants that live for one year)
Woody Stems
The hard stem, covered with bark or perennials (plants that live for many years)
Cambium
A special area of cell division between the xylem and phloem in plants
Bark
Thick layer of dead cells on the outside of woody stems
Bulb
A short underground stem with enlarged leaf bases for food storage (for example onion)
Tuber
A short, enlarged underground stem specialized for food storage (for example potato)
