Quizplus · Accepted Answer

In phagocytosis, the cytoplasmic extensions of the cell (such as pseudopods) surround the object being destroyed, forming a vesicle in the cytoplasm (step 3 and 4). This vesicle then fuses with a lysosome (step 2), activating digestive enzymes which break down the ingested material (step 5). Any residue is then ejected from the cell (step 1). The correct order is therefore 3, 4, 2, 5, 1, which corresponds with choice C.
