Final answer:
A vesicle fuses with a lysosome to release waste materials for disposal.
Step-by-step explanation:
A vesicle fuses with a lysosome in order to release waste materials for disposal. Lysosomes are specialized organelles that contain digestive enzymes capable of breaking down cellular waste and debris. When a vesicle fuses with a lysosome, the waste materials inside the vesicle are broken down by the enzymes in the lysosome, allowing for their disposal.
