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. Welcome to United States Botanic Garden. eFloras.org Home. Tropicos - Home. Archaeplastida. 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. 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.

Recommended this month New Book ** Edible Perennials: 50 Top perennials from Plants For A Future [Paperback] Current interest in forest or woodland garden designs reflects an awareness that permanent mixed plantings are inherently more sustainable than annual monocultures.
They safeguard and enrich soil ecosystems, enable plants to form cooperative combinations, make use of layers above and below the soil, and they create benign microclimates which soften winds and recycle the rain. The challenge is productivity: how can yields of useful foods and other useful materials be maximised? The latest book from Plants For A Future is a resource for discovering some of the answers.
Edible Perennials provides detailed information, attractively presented, on 50 selected perennial plants, based on practical experience and observation, plus a wide range of reputable sources.

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.
