The correct answer is: They break down worn-out cell parts that are no longer needed.

Lysosomes are membrane-bound organelles that contain digestive enzymes. They play a crucial role in the health of cells by breaking down and recycling cell debris, worn-out organelles, and cellular waste materials. This process, known as autophagy, helps to maintain the overall integrity and functionality of the cell.

The correct answer is: They break down worn-out cell parts that are no longer needed.

Lysosomes are membrane-bound organelles found in the cells of organisms. They contain powerful enzymes that function as the cell's recycling center. The primary function of lysosomes is to break down waste materials, like worn-out cell parts and foreign substances, that are no longer needed by the cell.

To find the correct answer, you can eliminate the other options by understanding the functions of each organelle mentioned:

1. They move proteins around the cell: This is the function of the endoplasmic reticulum (ER) and Golgi apparatus, not lysosomes.

2. They create cell boundaries and make cells rigid: This is the function of the cell membrane and cell wall, not lysosomes.

3. They allow cell organelles to move freely through the cell as needed: This is the function of the cytoplasm and cytoskeleton, not lysosomes.

By process of elimination, the correct answer is that lysosomes break down worn-out cell parts that are no longer needed, contributing to the overall health of cells.
