As explained by the University of Massachusetts Amherst, amoebas move by extending projections of their body. Once one of these projections, which are called pseudopods, is extended, it remains stationary, and the cytoplasm from the rest of the amoeba’s body moves into the pseudopod. The term "pseudopod" means “false foot.”Know More
Researchers at the University of Massachusetts Amherst, found that the locomotion of amoebas is related to the temperature of their environment. When the researchers subjected a sample of amoebas tocold water, they found that the single-celled organisms moved much more slowly and eventually stopped moving altogether.
Scientists at Virginia Tech are trying to construct robots that use locomotion styled after the ways amoebas move. Such flexible, shape-shifting designs are ideally suited for search and rescue missions, in which a robot may be forced to squeeze through tiny openings. Alternatively, these robots may be helpful for developing surgical robots that travel inside the human body.
According to WebMD, some amoebas are responsible for causing illness in humans. One such species, known to scientists as Naegleria fowleri, can cause serious problems as the organism feeds on brain tissue once inside the human body. Normally, the amoebas consume bacteria in their natural habitat.Learn more about Biology
Paramecium have tiny hair-like structures, called cilia, around the outer edge of their cell that move back and forth in a whip-like fashion, allowing movement in water. Paramecium normally attach to the bottom of a body of water, such as a pond, stream or puddle.Full Answer >
Locomotion in the protist kingdom is varied and extremely versatile. Amoebas use cytoplasmic processes called pseudopods, while paramecia have rows of cilia that move in unison like tiny oars. Euglena and dinoflagellates use whip-like proteins called flagella to swim, and some protozoa, such as diatoms and plasmodium (the organism that causes malaria), are non-motile, meaning they do not move independently.Full Answer >
The hydra freshwater polyp moves by attaching its tentacles to an object, then dragging itself or rolling in a cartwheel motion to its new location, usually a stick or leaf that has been submerged. It can also detach from its base to float freely on an air bubble for longer distance travel.Full Answer >
Slime molds move through cytoplasmic streaming where protein-rich material called micro-filaments, provide the means of locomotion and control mechanism that enables these organisms to move in a certain direction. Slime molds have been observed to move at speeds of 0.04 of an inch per hour.Full Answer >
