Food is taken into the cell by an oral groove (or gullet, as shown in Figure 9), where small particles of the food are phagocytosed into food vacuoles.
membranelle Short, transverse rows of cilia, fused at their bases, serving to move food particles toward the oral groove of a protozoan.
Instead of surrounding their prey like an amoeba, they take in the food through an oral groove (a protist version of a mouth). They even have a way of getting rid of the food through an anal pore.
