Archaeplastida. Die Archaeplastida sind eine der sechs Gruppen von Eukaryoten, also Lebewesen mit Zellkernen, die es nach der Systematik der Eukaryoten von Adl u.a. 2005 gibt.
Zu ihnen gehören die Grünalgen, die Rotalgen und die Pflanzen. Merkmale[Bearbeiten] Die Archaeplastida besitzen photosynthetisch aktive Plastiden mit Chlorophyll a als Hauptfarbstoff. Die Plastiden stammen von einer primären Endosymbiose mit einem Cyanobakterium. Die Plastiden können in manchen Gruppen sekundär verloren gegangen oder reduziert sein. Meist besitzen sie eine Zellwand aus Zellulose. Systematik[Bearbeiten] Adl u.a. gliedern die Archaeplastida in drei Gruppen ohne klassische Rangstufen: Literatur[Bearbeiten] Sina M.

The Archaeplastida (or Plantae sensu lato (in the broad sense)) are a major group of eukaryotes, comprising the red algae (Rhodophyta), the green algae and the land plants, together with a small group of freshwater unicellular algae called glaucophytes.[1] The chloroplasts of the glaucophytes are surrounded by two membranes, suggesting they developed directly from endosymbiotic cyanobacteria.
In all other groups, the chloroplasts are surrounded by three or four membranes, suggesting they were acquired secondarily from red or green algae. The cells of the Archaeplastida typically lack centrioles and have mitochondria with flat cristae. There is usually a cell wall including cellulose, and food is stored in the form of starch. However, these characteristics are also shared with other eukaryotes in the Kingdom Plantae. The main evidence that the Archaeplastida form a monophyletic group comes from genetic studies, which indicate that their plastids probably had a single origin.

Pacific Island Ecosystems at Risk (PIER) home page. Plant Threats to Pacific Ecosystems - index to PIER lists. Global Invasive Species Database. The Global Invasive Species Database (GISD) aims to increase awareness about invasive alien species and to facilitate effective prevention and management activities. It is managed by the Invasive Species Specialist Group (ISSG) of the SSC- Species Survival Commission of the IUCN -International Union for Conservation of Nature. The GISD was developed as part of the global initiative on invasive species led by the Global Invasive Species Programme GISP and was/is supported through partnerships with the National Biological Information Infrastructure (NBII), Manaaki Whenua-Landcare Research and the University of Auckland.
The GISD focuses on invasive alien species that threaten native biodiversity and natural ecosystems and covers all taxonomic groups from micro-organisms to animals and plants in all ecosystems. Species information is either supplied by or reviewed by expert contributors from around the world.
