Explanation: 

Detailed explanation-1: -LYSOSOMES are organelles produced by the Golgi apparatus that contain powerful protein digesting enzymes. Lysosomes are responsible for the breakdown and absorption of materials taken in by the cell.

Detailed explanation-2: -Answer and Explanation: The lysosome is the organelle that digests macromolecules, worn out cell parts, debris, and disease-causing microbes.

Detailed explanation-3: -Lysosomes break down macromolecules into their constituent parts, which are then recycled. These membrane-bound organelles contain a variety of enzymes called hydrolases that can digest proteins, nucleic acids, lipids, and complex sugars. The lumen of a lysosome is more acidic than the cytoplasm.

Detailed explanation-4: -Lysosomes are membrane-enclosed organelles that contain an array of enzymes capable of breaking down all types of biological polymers-proteins, nucleic acids, carbohydrates, and lipids.
