  • 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.

      • Aquatic Organisms 0 questions
        • Plancton 0 questions Community of tiny aquatic organisms, both PLANTS and ANIMALS, that are either free-floating or suspended in the water, with little or no power of locomotion. They are divided into PHYTOPLANKTON and ZOOPLANKTON.
          • Phytoplancton 0 questions Ensemble d'algues microscopiques qui flottent dans les eaux. Ce sont des cellules photosynthétiques. Ce terme ne correspond pas à une réelle taxonomie mais fait référence à un mode de vie (utilisation énergétique et mobilité). La plupart sont des ALGUES (ALGAE) unicellulaires. Ces groupes très importants incluent les DIATOM
          • Zooplancton 0 questions Minute free-floating animal organisms which live in practically all natural waters.
        • Algue Marine 0 questions Marine ALGAE widely distributed in the ocean, occurring from the tide level to considerable depths, free-floating (planktonic) or anchored to the substratum (benthic). They lack a specialized vascular system but take up fluids, nutrients, and gases directly from the water. They contain CHLOROPHYLL and are photosynthetic, but some also contain other light-absorbing pigments. Many are of economic importance as FOOD, fertilizer, AGAR, potash, or source of IODINE.
      • 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.
      • 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 166 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.
