Explanation:
Detailed explanation-1: -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-2: -They cannot digest themselves due to the glycocalyx protective layer. It is formed by the carbohydrate moiety of the membrane proteins and lipids. The membrane protein and lipid are highly glycosylated as a result making it resistant to digestion by hydrolases and protecting the phospholipid bilayer.
