Verified step by step guidance

Understand the role of hydrolytic enzymes: These enzymes are responsible for breaking down biomolecules through the addition of water, a process known as hydrolysis.

Identify the function of lysosomes: Lysosomes are membrane-bound organelles that contain hydrolytic enzymes. They are involved in digesting excess or worn-out organelles, food particles, and engulfed viruses or bacteria.

Consider the need for segregation: Hydrolytic enzymes need to be contained within a specific organelle to prevent them from digesting essential cellular components. Lysosomes provide this containment.

Review the structure of lysosomes: Lysosomes have a single membrane that isolates their acidic environment and enzymes from the rest of the cell, ensuring that the enzymes only act on intended targets.

Compare with other organelles: While the rough ER, smooth ER, central vacuole, and Golgi apparatus have important roles, they do not primarily function to contain hydrolytic enzymes like lysosomes do.
