Detailed explanation-1: -The digestive enzymes of lysosomes breakdown unwanted (waste) substances and worn out cell parts. Hence, they can be considered as the waste disposal system of the cell.

Detailed explanation-2: -Cells also have to recycle compartments called organelles when they become old and worn out. For this task, they rely on an organelle called the lysosome, which works like a cellular stomach.

Detailed explanation-3: -Lysosomes and peroxisomes. These organelles are the recycling center of the cell. They digest foreign bacteria that invade the cell, rid the cell of toxic substances, and recycle worn-out cell components.

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.

Detailed explanation-5: -In the process, the researchers found that lysosomes-the cell’s protein “recycling centers”-help govern cell division decisions.
