Final answer:
A scavenger white blood cell, notably a macrophage, would have a large number of lysosomes (option B), which help in destroying pathogens through the process of phagocytosis.
Step-by-step explanation:
A scavenger white blood cell, like a macrophage, most likely has a large number of lysosomes. These specialized organelles are essential for the immune response, contributing to the destruction of pathogens through phagocytosis. A macrophage captures potentially harmful bacteria or other particles into a vesicle that fuses with a lysosome.
Within the lysosomes, hydrolytic enzymes then break down these invaders, thereby protecting the organism from infections and diseases. Lysosomes are therefore known as the cellular "digestive system" due to their ability to degrade various types of biomolecules.
It's also informative to note that organelles like mitochondria produce large quantities of ATP, critical for energy demands in cells such as muscle cells. In this context, they are referred to as the cell's "powerhouses." However, for a cell tasked with engulfing and destroying pathogens like macrophages, lysosomes are the key players in management of intracellular digestion and cellular waste.
