In white blood cells, what contributes to phagocytes?
A.
Lysosomes.
B.
Golgi apparatus
C.
Vacuoles
D.
Endoplasmic reticulum
The correct answer is:
A. Lysosomes
Explanation:
Lysosomes are organelles in white blood cells (such as phagocytes) that contain digestive enzymes. These enzymes help break down and digest engulfed pathogens and debris during the process of phagocytosis. Lysosomes fuse with phagosomes (vacuoles containing ingested material) to form phagolysosomes, where the digestion occurs.
- B. Golgi apparatus: Involved in modifying, sorting, and packaging proteins and lipids, but not directly in phagocytosis.
- C. Vacuoles: Involved in the storage and transport of materials within the cell, but not specifically in the digestion of pathogens.
- D. Endoplasmic reticulum: Involved in the synthesis of proteins and lipids but does not directly contribute to the phagocytic process.
