Types Of Stems
Different types of stems: axis of a plant.
- Stolon: running stems, which trail above the ground.
- Tuber: subterranean swellings of plant axes.
- Volubilate twining: a stem that will wind around objects for support.
- Section of a bulb: division of a bulb that allows study of the interior.
- Bulb: plant organ that allows for the growth of the plant every year.
- Rhizome: stem that annually produces adventitious roots.
HERBACEOUS STEMS: They do not have developed ligneous stiffened structures. They are
generally frail. We find them in plants like the following:
Annual plants: Plants with a year life-time. Weeds generally belong to this group.
Vivacious plants:Plants with aerial stems lastinga single season, but keeping underground structures from which new stems spring again next season.
LIGNEOUS STEMS: They have developed rigid, stiffened structures, what we normally know as “wood” . According to the height they attain we classify them into:
Trees: Plants with ligneous stems, with a superior height of five meters. In this case we call
the stems trunks. They do not generally branch up to a considerable distance from the soil.
