Question

cell structures quick check
why are lysosomes important to the health of cells? (1 point)
○ they allow cell organelles to move freely through the cell as needed.
○ they create cell boundaries and make cells rigid.
○ they move proteins around the cell.
○ they break down worn-out cell parts that are no longer needed.

Explanation:

To determine the correct answer, we analyze the function of lysosomes:

• The first option describes a function related to cytoskeleton or cytoplasm's role in organelle movement, not lysosomes.
• The second option refers to cell walls (in plant cells) or cell membranes, not lysosomes.
• The third option is the function of vesicles or the endomembrane system for protein transport, not lysosomes.
• Lysosomes are known as the "digestive system" of the cell, breaking down waste materials, worn - out organelles, etc. So the fourth option correctly describes the function of lysosomes.

Answer:

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