Answer:
Digestion of the food particle occurs in a vesicle enclosed by a membrane that separates the digestion from the cytoplasm.
Explanation:
A food vacuole is a digestive organelle present in the protozoans which contains the enzymes responsible for digestion. The food vacuole is membrane-bound organelle thus separates the food particles from the cytoplasm of the cell.
The digestive enzymes like proteases, DNases, RNases, lipase and many other enzymes digest the macromolecules and convert them to simple compounds. These nutrients are then used by the organism for the growth of the cell.
Thus, the selected option is correct.
