  • Anatomie 93 questions
  • Organismes 37 questions Any living biological entity, such as an animal, plant, fungus, or bacterium.
    • Eukaryota 3 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.
    • Bactéries 14 questions Bactéries, gram-positif, formant des endospores. Elles comprennent les genres suivants : BACILLUS ; CLOSTRIDIUM ; MICROMONOSPORA ; SACCHAROPOLYSPORA et STREPTOMYCES.
    • Virus 2 questions Petits agents infectieux aux génomes constitués, soit d'ADN, soit d'ARN (jamais des deux), sans métabolisme propre et dans l'incapacité de se multiplier en dehors des cellules vivantes.
    • Organism Forms 0 questions
      • Aquatic Organisms 0 questions
      • Formes Bactériennes Atypiques 0 questions Microorganisms that have undergone greater changes than normal in morphology, physiology, or cultural characteristics.
      • Chimère 0 questions An individual that contains cell populations derived from different zygotes.
      • Endophytes 0 questions
      • Hermaphroditic Organisms 0 questions
      • Lichens 0 questions Any of a group of plants formed by a mutual combination of an alga and a fungus.
      • Life Cycle Stages 0 questions The continuous sequence of changes undergone by metamorphosing insects and other animals during the post-embryonic development process.
        • Larve 0 questions Wormlike or grublike stage, following the egg in the life cycle of insects, worms, and other metamorphosing animals.
        • Nymphe 0 questions The immature stage in the life cycle of those orders of insects characterized by gradual metamorphosis, in which the young resemble the imago in general form of body, including compound eyes and external wings; also the 8-legged stage of mites and ticks that follows the first moult.
        • Oocystes 0 questions Zygotes encapsulés des protozoaires sporozoaires. Dans son développement, l'oocyste produit de petits organismes infectieux individuels appelés SPOROZOITES. Ensuite, en fonction du genre, l'oocyste entier est appelé sporocyste, ou l'oocyste contient des sporocystes multiples encapsulant des sporozoïtes.
          • Sporozoïtes 0 questions The product of meiotic division of zygotes in parasitic PROTOZOA comprising haploid cells. These infective cells invade the host and undergo asexual reproduction producing MEROZOITES (or other forms) and ultimately gametocytes.
        • Pupe 0 questions An inactive stage between the larval and adult stages in the life cycle of insects.
        • Schizontes 0 questions Multinucleate cells or a stage in the development of sporozoan PROTOZOA. It is exemplified by the life cycle of PLASMODIUM FALCIPARUM in the MALARIA infection cycle.
        • Trophozoïtes 0 questions Cells or feeding stage in the life cycle of sporozoan PROTOZOA. In the malarial parasite, the trophozoite develops from the MEROZOITE and then splits into the SCHIZONT. Trophozoites that are left over from cell division can go on to form gametocytes.
      • Mycorrhizae 0 questions Symbiotic combination (dual organism) of the MYCELIUM of FUNGI with the roots of plants (PLANT ROOTS). The roots of almost all higher plants exhibit this mutually beneficial relationship, whereby the fungus supplies water and mineral salts to the plant, and the plant supplies CARBOHYDRATES to the fungus. There are two major types of mycorrhizae: ectomycorrhizae and endomycorrhizae.
      • Organismes Génétiquement Modifiés 0 questions Organisms whose GENOME has been changed by a GENETIC ENGINEERING technique.
      • Spores 0 questions Eléments reproducteurs des organismes inférieurs, tels que les bactéries, les protozoaires, les champignons et les plantes cryptogamiques.
      • Chimère Obtenue Par Transplantation 0 questions An organism that, as a result of transplantation of donor tissue or cells, consists of two or more cell lines descended from at least two zygotes. This state may result in the induction of donor-specific TRANSPLANTATION TOLERANCE.
  • Maladies 167 questions Any impairment of normal physiological function affecting all or part of an organism, esp a specific pathological change caused by infection, stress, etc, producing characteristic symptoms; illness or sickness in general.
  • Produits chimiques et pharmaceutiques 79 questions Any substance used in or resulting from a reaction involving changes to atoms or molecules, especially one derived artificially for practical use and any synthetic, semisynthetic, or natural chemical substance used in the treatment, prevention, or diagnosis of disease, or for other medical reasons.
