The small saclike structure that degrades waste products is called a lysosome.

Here's why:

* Lysosomes are membrane-bound organelles found in eukaryotic cells. They are like the "recycling centers" of the cell.

* They contain powerful enzymes that can break down various waste products. These include worn-out organelles, bacteria, and other cellular debris.

* This process is called "phagocytosis," where the lysosome engulfs the waste and breaks it down into smaller molecules that the cell can reuse or expel.
