These unicellular, complex organisms move via rows of cilia. They have many organs including a gullet, or mouth, food vacuoles, and an ectopract. They also have a contractile vacuole that balances water like a kidney. Their micronuclei is used for reproduction, and the macronuclei is used for protein synthesis.
Amoebas have pseudopodia, or false feet.
Proteins, like those found in a human's muscle, contract and relax their pseudopodia enabling them to move. Most amoebas are harmless. However, not all of them are. Some cause illnesses like amoebic dysentary. Amoebas eat by a process called phagocytosis.
