What structure enables a protozoan to get food into its mouth?

In protozoans, the structure that enables them to take in food is called the cytostome, or "cell mouth." This specialized structure allows the organism to engulf food particles through a process known as phagocytosis. In some protozoans, cilia or flagella may help create water currents to direct food toward the cytostome. Once the food is ingested, it is enclosed in a food vacuole for digestion.
