Chlorobionta
The Chlorobionta (Chlorobiontes) or Viridiplantae define the whole of the organizations usually recognized like the “green plants”. They form a group monophyletic including/understanding the terrestrial green algas and plants.
They are in particular characterized by the presence of Chlorophylle has and chlorophyl B. They correspond to the typical image of the plant, of green color, chlorophyls generally not being masked by other pigments.
Certain species are unicellular, much are pluricellular.
They count representatives as various as the Chlamydomonas , lettuce of sea ( Ulva lactuca ), the acétabulaires (kind Acetabularia ), the spirogyres (kind Spirogyra ), the pleurocoques ones (kind Pleuroccus ), the Welwitschia mirabilis , the daisy ( Bellis perennis ), teak ( Tectona grown ), the lily martagon ( Lilium martagon ), etc
On the other hand, all the “plants” are not of Chlorobiontes. Other chlorophyllian organizations Eucaryote S can belong to different groups. Thus the Rhodobiontes, or red algas, form a distinct but rather nearby group, while the brown algas and many chlorophyllian unicellular organizations belong to more distant evolutionary groups.
Chlorobiontes subdivide themselves into two clades principal, the Chlorophyta which gather the majority of the green algas most known and the Streptophyta which gather certain particular green algas and all the terrestrial plants.
Chlorobiontes hold a considerable ecological place on ground, representing all the terrestrial vegetation and a big part of the biomass of the oceans.
Classification
Chlorobiontes train the group-brother of the Rhodobionta or Rhodophyta, the red algas. With, moreover, the Glaucophyta, they constitute the whole of the Archaeplastida, or “green line”.
Within the group, the Charophyta were detached from the Chlorophyta and constitute, with the Embryophyta, the clade of the Streptophyta.
The Pleurastrophyceae were restricted with the Trebouxiophyceae. The Prasinophyceae and the Charophyta appeared paraphyletic, and constitute the base respectively Chlorophyta and Streptophyta.
The Bryophyta and the Pteridophyta are also paraphyletic and constitute each one several clades.
