Show answer and explanation

Correct answer: (b) Lysosomes

Explanation

Lysosomes are called the suicidal bags of the cell. They are small sacs of digestive enzymes (acid hydrolases) that break down proteins, fats, carbohydrates and nucleic acids. They digest food particles, invading bacteria and worn-out organelles.

When a cell is damaged or dies, its lysosomes burst and their enzymes digest the cell itself. This is called autolysis, which is why lysosomes are called suicidal bags.

Ribosomes make proteins, the Golgi packs and sends materials, and mitochondria make ATP.
