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