Types Of Stems

Version 1

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.

 

Version 2

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.

Shrubs:Are those plants with ligneous stems, from one to five meters tall. In this case,

branching begins at soil level.

 

Bushes : Ligneous plants shorter than one meter tall.
