Solution:

Lysosomes are formed by budding off vesicles from the Golgi apparatus They are bound by a single membrane about 500 nm. They are involved in intracellular digestion and contain the enzymes needed to digest all types of macromolecules. The enzymes present in such vesicles belong to acid hydrolases: The acidic condition is maintained by pumping protons into the interior of lysosomes. These are the organelles that are involved in the process of phagocytosis.
