Which of the following organelles is most abundant in those animal cells which exhibit phagocytic activity?
Correct answer: C. Lysosomes
- A. Golgi apparatus
- B. Cell wall
- C. Lysosomes
- D. None of these
Explanation
Lysosomes are most abundant in those animal cells which exhibit phagocytic activity. Phagocytic cells are cells that engulf and destroy foreign particles, such as bacteria. Lysosomes are organelles that contain enzymes that break down cellular waste products and foreign substances. Phagocytic cells, such as macrophages and neutrophils, have a large number of lysosomes. This is because they need to be able to break down the foreign particles that they engulf. The lysosomes fuse with the phagosome, which is the vesicle that contains the foreign particle, and the enzymes in the lysosomes then break down the particle. The abundance of lysosomes in phagocytic cells is an important adaptation that allows these cells to defend the body against infection.
