White blood cells are involved in protecting the body from infections. A monocyte, shown below, is one type of white blood cell. When microbes or other pathogens enter the body, monocytes travel to the point of infection. There, they take in the pathogens and break them down to destroy them. How does the structure of a monocyte relate to its function? A. It has a small Golgi apparatus, which ensures it can make antibodies to prevent infections. B. It has a large nucleus, which helps it take up microbes and other pathogens. C. It has few mitochondria, which ensure it has enough ATP to break down organic molecules. D. It has many lysosomes, which help it digest bacteria and other foreign materials.
