Not all parts of any given plant are edible but all parts of edible plants have been known to figure as raw or cooked food: leaves, roots, tubers, stems, seeds, buds, fruits, and flowers. The most commonly edible parts of plants are FRUIT, usually sweet, fleshy, and succulent. Most edible plants are commonly cultivated for their nutritional value and are referred to as VEGETABLES.

              • Angiospermes 1 question Any member of the more than 250,000 species of flowering plants. Angiosperms are often differentiated from GYMNOSPERMS by their production of seeds within a closed chamber (OVARY, PLANT). The Angiosperms division is composed of two classes, the monocotyledons (Liliopsida) and dicotyledons (Magnoliopsida).
              • Anthocerotophyta 0 questions A plant division that includes hornworts, named for the horn-like appearance of the spore-producing plant (sporophyte).
              • Bryophyta 0 questions Groupe du règne végétal. Les bryophytes comprennent le sous-groupe des mousses, lesquelles comprennent les classes suivantes : Andreaeopsida, bryopsida et sphagnosida.
                • Bryopsida 0 questions Classe de plantes appartenant aux Bryophytes, comprenant les mousses qui sont retrouvées dans des milieux humides (y compris dans l'eau), mais aussi dans des milieux plus secs. Les mousses possèdent des tiges sans feuille érigées ou couchées. Les spores formées dans les capsules sont libérées et se développent pour donner de nouvelles plantes. Beaucoup de petites plantes portent le nom de mousse et n'en sont pas. La mousse trouvée sur le face nord des arbres est en réalité une algue verte; la mousse d'Irlande est, en fait, une algue rouge, etc.
                • Sphagnopsida 0 questions Classe de bryophytes qui est surtout connue pour la sphaigne formant la tourbe des marais.
              • Equisetum 0 questions The only living genus of the order Equisetales, class Equisetopsida (Sphenopsida), division Equisetophyta (Sphenophyta); distantly related to ferns. It grows in moist places. The hollow, jointed, ridged stems contain SILICATES.
              • Fougères 0 questions Seedless nonflowering plants of the class Filicinae. They reproduce by spores that appear as dots on the underside of feathery fronds. In earlier classifications the Pteridophyta included the club mosses, horsetails, ferns, and various fossil groups. In more recent classifications, pteridophytes and spermatophytes (seed-bearing plants) are in the division, or phylum, Tracheophyta.
              • Gymnospermes 0 questions Les gymnospermes sont un groupe de plantes vasculaires dont les graines ne sont pas enfermées dans un ovaire qui a mûri (un fruit), en contraste avec les angiospermes dont les graines sont entourées d'une paroi ovarienne. Les graines de nombreux gymnospermes (littérallement "graine nue") sont contenues en cônes et ne sont pas visibles. Les taxinomistes identifient maintenant quatre divisions distinctes parmi les plantes gymnospermes existantes (les coniferophyta, les cycadophyta, les ginkgophyta et les gnétophyta).
              • Hepatophyta 0 questions A plant division. They are simple plants that lack vascular tissue and possess rudimentary rootlike organs (rhizoids). Like MOSSES, liverworts have alternation of generations between haploid gamete-bearing forms (gametophytes) and diploid spore-bearing forms (sporophytes).
              • Lycopodiaceae 0 questions The club-moss plant family of the order Lycopodiales, class Lycopodiopsida, division Lycopodiophyta, subkingdom Tracheobionta. The common name of clubmoss applies to several genera of this family. Despite the name this is not one of the true mosses (BRYOPSIDA ).
              • Selaginellaceae 0 questions A plant family of the order Selaginellales, class Lycopodiopsida, division Lycopodiophyta, subkingdom Tracheobionta. Members contain bilobetin. The rarely used common name of resurrection plant is mainly used with CRATEROSTIGMA.
      • Retortamonadidae 0 questions
      • Rhizaria 0 questions
      • Stramenopiles 0 questions
    • Archéobactéries 0 questions One of the three domains of life (the others being BACTERIA and Eukarya), formerly called Archaebacteria under the taxon Bacteria, but now considered separate and distinct. They are characterized by: (1) the presence of characteristic tRNAs and ribosomal RNAs; (2) the absence of peptidoglycan cell walls; (3) the presence of ether-linked lipids built from branched-chain subunits; and (4) their occurrence in unusual habitats. While archaea resemble bacteria in morphology and genomic organization, they resemble eukarya in their method of genomic replication. The domain contains at least four kingdoms: CRENARCHAEOTA; EURYARCHAEOTA; NANOARCHAEOTA; and KORARCHAEOTA.
