Light micrograph of two amoebae,Amoeba proteus,meeting and touching each other with their numerous pseudopodia (false feet). The pseudopodia are finger-like extensions of the cell cytoplasm,used both in locomotion and feeding. Feeding occurs by phagocytosis. A pseudopod flows out and engulfs small organisms and is then reabsorbed into the cell body,where the victim is digested by enzymatic action within a food vacuole. The dark spot seen within each amoeba is the cell nucleus. Magnification: x160 at 35mm size | |
