“…The plasmodium is a streaming packet of cytoplasm containing many nuclei. In the plasmodial stage, P. polycephalum exhibits an amoeboid type of movement and is known to respond to a variety of environmental stimuli, including light, physical barriers, food sources, and chemical repellants (Nakagaki et al, 2000(Nakagaki et al, , 2007Adamatzky, 2010;Latty & Beekman, 2010). This response can be easily observed with the naked eye as the plasmodium grows, creating new pseudopodia and thickening tubes in some areas and shrinking back pseudopodia and allowing tubes to die in other areas (tubes that were once alive appear white rather than yellow).…”
