vegetative organs การใช้

The vegetative organs are essential for maintaining the life of a plant.
Bladderworts are unusual and highly specialized plants, and the vegetative organs are not clearly separated into roots, stems as in most other angiosperms.
In more advanced aneurophytaleans such as " Aneurophyton " these vegetative organs started to look rather more like fronds, and eventually during Late Devonian times the aneurophytaleans are presumed to have given rise to the pteridosperm order, the Lyginopteridales.
The stratigraphically oldest known examples belong to the Middle Devonian order the Aneurophytales, with forms such as " Protopteridium ", in which the vegetative organs consisted of relatively loose clusters of axes . " Tetraxylopteris " is another example of a genus lacking leaves.
While there can be 11 organ systems in animals, there are far fewer in plants, where some perform the vital functions, such as photosynthesis, while the reproductive organs are essential in asexual vegetative reproduction, the vegetative organs are those that create the new generation of plants ( see clonal colony ).
