Phagocytosis, autophagy and extracellular digestion are the functions of:
Correct answer: A. Lysosomes
- A. Lysosomes
- B. Mitochondria
- C. Golgi apparatus
- D. All of these
Explanation
The correct answer is lysosomes. Lysosomes are specialized vesicles within cells that contain hydrolytic enzymes to break down biomolecules. They are crucial for phagocytosis (engulfing and digesting large particles), autophagy (recycling the cell's own components), and extracellular digestion (releasing enzymes to digest materials outside the cell). Mitochondria, on the other hand, are involved in energy production and cellular respiration. The Golgi apparatus is responsible for processing and packaging proteins and lipids. Therefore, these other organelles do not perform the functions described in the question.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
