a membrane-bound organelle that serves as the sites of cellular digestion and contains digestive enzymes that break down worn-out cell parts is what?

1 answer

The organelle you are referring to is called a lysosome. Lysosomes contain various digestive enzymes that break down waste materials and cellular debris, playing a critical role in the recycling of cellular components. They are often described as the "cell's stomach" because of their function in digesting and recycling macromolecules and other cellular components.
