Question

How does a cell rid itself of defective or malfunctioning organelles?

• A. They are engulfed by plastids and stored until export from cell is possible
• B. Defective parts accumulate until the cell itself dies
• C. They are exported by exocytosis
• D. Lysosomes assist in the removal of defective organelles by digesting them

Answer 1

The correct option is D Lysosomes assist in the removal of defective organelles by digesting them

The lysosomes may be called "suicide bags" of the cell in view of their autolytic role, or "disposal units" of the cell because they digest the incoming food materials and remove the foreign bodies, toxic molecules, and debris; or "recycling centres" as they break down warn out and defective cells and cell organelles to component molecules for building new organelles and cells.
