The cell organelles filled with enzymes needed to break down certain materials in the cell are called lysosomes.

Here's a breakdown:

* Lysosomes: These are membrane-bound organelles that contain a variety of hydrolytic enzymes. These enzymes are capable of breaking down various biomolecules, including proteins, carbohydrates, lipids, and nucleic acids.

* Function: Lysosomes act as the cell's "recycling center" and "garbage disposal." They break down worn-out organelles, engulfed bacteria and viruses, and cellular debris.

* Other roles: They also play roles in cellular processes such as:

* Apoptosis (programmed cell death)

* Cell signaling

* Repair of cellular damage
