A moving cell is cylindrical in shape, with a single hemispherical pseudopod at the front and a semipermanent projection called a uroid at the back, which is covered in tiny non-motile flagella. They consume a wide variety of food, and have many vacuoles containing both food, such as diatoms, and debris such as sand.
How does Pelomyxa reproduce?
Reproduction occurs by plasmatomy of multinucleate amoebae: they form division rosettes or divide unequally. The cytoplasm clearly differentiated into ectoplasm and endoplasm. Vesicular nuclei (1-32 per cell) with a single central nucleolus. Nuclear envelope surrounded with microtubules in all life cycle stages.
How does Chaos amoeba move?
Like other lobose amoebae, Chaos move by extending pseudopodia. As a new pseudopod is extended, a variable zone of ectoplasm forms at the leading edge and a fountaining stream of endoplasm circulates within.
