Which organelle plays a primary role in intracellular digestion within eukaryotic cells?

• A. Lysosome
• B. Nucleus
• C. Mitochondrion
• D. Golgi apparatus

Answer: (A)

Verified step by step guidance

1. Understand the function of intracellular digestion: Intracellular digestion refers to the breakdown of macromolecules, cellular debris, and foreign particles within the cell.
2. Review the role of lysosomes: Lysosomes are membrane-bound organelles containing hydrolytic enzymes that break down biomolecules such as proteins, lipids, carbohydrates, and nucleic acids. They are specialized for intracellular digestion.
3. Compare the functions of the other organelles: The nucleus is responsible for storing genetic material and regulating gene expression, the mitochondrion is involved in energy production through cellular respiration, and the Golgi apparatus is responsible for modifying, sorting, and packaging proteins and lipids.
4. Identify the organelle most suited for intracellular digestion: Based on the functions described, lysosomes are the organelles specifically designed for breaking down materials within the cell.
5. Conclude that lysosomes play the primary role in intracellular digestion within eukaryotic cells, as they contain the necessary enzymes and structure for this process.
