in the nucleus, mitochondria and chloroplasts

all animals are made from cell

theodor schwann

during an infection white blood cells travel to the infected site and phagocytize the pathogens. after phagocytosis primary lysosomes fuse with the phagocytic vesicle to form a larger vesicle called a secondary lysosome. the reason for this is

to mix pathogens with strong hydrolytic enzymes and destroy them
