    Life cycle. Dictyostelium discoideum is a species of soil-dwelling amoeba belonging to the phylum Amoebozoa, infraphylum Mycetozoa.Commonly referred to as slime mold, D. discoideum is a eukaryote that transitions from a collection of unicellular amoebae into a multicellular slug and then into a fruiting body within its lifetime.

  3. Dictyostelid - Wikipedia

    en.wikipedia.org/wiki/Dictyostelid

    A petri dish of Dictyostelium.. When food (normally bacteria) is readily available dictyostelids behave as individual amoebae, which feed and divide normally. However, when the food supply is exhausted, they aggregate to form a multicellular assembly, called a pseudoplasmodium, grex, or slug (not to be confused with the gastropod mollusc called a slug).

    en.wikipedia.org/wiki/Symbiosis_in_Amoebozoa

    Giant viruses, or nucleocytoplasmic large DNA viruses, frequently infect Amoebozoa and other protists causing amoeba lysis and cell rounding in 12 hours and amoeba population collapse in 55 hours. [3] As such, there is a strong selective pressure on both Amoebozoa and their symbionts to resist these viruses.

  7. Pseudopodia - Wikipedia

    en.wikipedia.org/wiki/Pseudopodia

    Amoeba proteus extending lobose pseudopodia. A pseudopod or pseudopodium (pl.: pseudopods or pseudopodia) is a temporary arm-like projection of a eukaryotic cell membrane that is emerged in the direction of movement. Filled with cytoplasm, pseudopodia primarily consist of actin filaments and may also contain microtubules and intermediate filaments.

  8. Protist locomotion - Wikipedia

    Temperature is a key environmental factor for living organisms because chemical reaction rates and physical characteristics of biological materials can change substantially with temperature. Living organisms acclimate to cold and heat stress using acquired mechanisms, including the ability to migrate to an environment with temperatures suitable ...
