21. Arcellinid testate amoebae produce lobose ( wide ) pseudopodia while euglyphid testate amoebae produce filose ( slender ) pseudopods. 22. Arcellinid testate amoebae produce lobose ( wide ) pseudopodia while euglyphid testate amoebae produce filose ( slender ) pseudopods. 23. "' Faustovirus "'is a genus of giant virus which infects amoebae associated with humans. 24. This forms a cellular aggregate and at the center of the aggregate the zygote giant cell ingests the surrounding amoebae . 25. Arcellinid testate amoebae are commonly found in soils, leaf litter, peat bogs and near / in fresh water. 26. The name Lobosa was chosen for these amoebae " as expressing the lobe-like character of their pseudopodial extensions ." 27. Shell-building by amoebae reveals complex discrimination and manipulative skills that are ordinarily thought to occur only in multicellular organisms. 28. The introns are closely related to group I introns in the 23S rRNA of chloroplasts and mitochondria in algae and amoebae . 29. In about 10 % of invasive cases the amoebae enter the bloodstream and may travel to other organs in the body. 30. Amoebae typically ingest their food by phagocytosis, extending pseudopods to encircle and engulf live prey or particles of scavenged material.
