- Amoeboid movement
expert date July 2010 one source date July 2010 Amoeboid movement is a crawling like type of movement accomplished by protrusion of cytoplasm of the Cell biology cell involving the formation of pseudopod ia. The cytoplasm slides and forms a pseudopodium in front to move the cell forward. This type of movement has been linked to changes in action potential the exact mechanism is still unknown. This type of movement is observed in amoeboids , slime mold s and some protozoa ns, as well as some cells in humans such as white blood cell leukocytes . Sarcoma s, or cancers arising from connective tissue cells, are particularly adept at amoeboid movement, thus leading to their high rate of metastasis. ref Stefano F. Cannibalism A way to feed on metastatic tumors Cancer Letters 258 2007 155 164 ref Locomotion of amoeba occurs due the sol gel conversion of the cytoplasm within its cell. The Ectoplasm cell biology ectoplasm being called the plasma gel and the endoplasm the plasma sol. The conversion of the endoplasm to ecto and vice versa is called sol gel conversion. citation needed date October 2010 For example, when an amoeba moves, it extends the gelatinous cytosol pseudopium, which then results in the more fluid cytosol flowing after the gelatinous portion where it congeals at the end of the pseudopium. Inside the amoeba, there are proteins that can be activated to convert the gel into the more liquid state.

- Grex (biology)
A grex or slug is a multicellular aggregate of amoeboid amoeba of the groups Acrasiomycota or Dictyosteliid a that can be formed when the amoeba run out of food. It takes its form when the column formed from the aggregation of cells collapses due to its height, and becomes a slug shaped mass. The grex moves as a unit, and the individual organisms form a fruiting body , in which amoeba are differentiated into stalk cells and spore cells. The latter can be transported by wind or water a distance that is relatively great compared with what the organisms can achieve in their typical form the former desiccate and die. Its name comes from the latin word meaning flock . See also Dictyosteliid References Zimmer, C. 1998. The slime alternative. Discoverer , 19 9 , 86 93.
