Verified step by step guidance

Understand the role of plasma cells: Plasma cells are specialized white blood cells that produce antibodies, which are proteins that help the immune system identify and neutralize foreign objects like bacteria and viruses.

Identify the origin of plasma cells: Plasma cells are derived from B lymphocytes (B cells), which are a type of white blood cell involved in the adaptive immune response.

Consider the lifespan of plasma cells: After producing antibodies, plasma cells typically have a short lifespan, as their primary function is to secrete antibodies during an immune response.

Evaluate the statement about direct pathogen attack: Plasma cells do not directly attack pathogens. Instead, they produce antibodies that bind to antigens on pathogens, marking them for destruction by other immune cells.

Determine the false statement: Based on the understanding that plasma cells produce antibodies and do not directly attack pathogens, the statement 'Plasma cells can directly attack pathogens' is false.
