Protozoa are generally motile, unicellular or syncytial, wall-less heterotrophic protists. They may be free living predators or scavengers, ingesting other organisms or bits of organic matter, or parasites or mutualistic symbionts.
Phylum Rhizopoda : Amoebas Phylum Rhizopoda contains about 200 species. The Amoeba proteus, commonly called the Amoeba is one of the most thoroughly studied protists. This formless group of organisms use pseudopodia for movement and feeding. These organisms are found worldwide, in soil, in salt and fresh water, and in the bodies of animals. The species Entamoeba histolytica, can cause a serious disease in humans if it finds its way into the intestine. These organisms are usually naked, though some have a hard shell called a test. They do not contain cilia or flagella. They never undergo meiosis and do not produce mitotic spindles during cell division. They are capable of changing direction indefinitely.

No. Ameba has PSEUDOPODs (like WBCs) that do the cytoplasmic streaming, and thus can go in any direction they "chose-not"
However there are planktonic amebae too that are in skeletons that are in the water column or a part of sediment, so they may not move as much as some species and are at the mercy of the currents. See foraminiferans and radiolarians for more info.

no, ameba moves by cytoplasmic streamingwhich means that it can collect its cytoplasm in one direction & can move at that side. same is true 4 other side also.
