Which process is responsible for the formation of food vacuoles in cells?

Phagocytosis is a cellular process in which cells engulf and digest particles such as bacteria, debris, and other cells. In the case of food vacuoles, cells use phagocytosis to engulf food particles. The food is pushed towards the cell, where the membrane bends inwards, forming a pocket called a phagosome. The phagosome then fuses with lysosomes, which contain digestive enzymes, forming a food vacuole. The enzymes break down the food, and the resulting nutrients are absorbed by the cell. Therefore, the process responsible for the formation of food vacuoles in cells is phagocytosis.
