If you mean "paramecium", it is a one celled creature. paramecium- move with cilia
amoeba- move by creeping along with their pseudopod's (foot-like appendage)
also, paramecium are larger.
They are considered eukaryotic cells because they have a true ("eu") nucleus.
paramecium has an organelle called the contractile vacuole,since it is hypertonic water rushes in from its habitat but this vacuole excretes the water constantly so that the cell do not burst.
