Detailed explanation-1: -Plasma cells are differentiated B-lymphocyte white blood cells capable of secreting immunoglobulin or antibodies. These cells play a significant role in the adaptive immune response, namely, being the main cells responsible for humoral immunity.

Detailed explanation-2: -Plasma cells are key to the immune response because they secrete antibodies. Given that antibodies are made of protein, which membrane-enclosed cell organelle would you expect the plasma cells to have in abundance? Which organelle would you expect to play the largest role in total cell destruction?

Detailed explanation-3: -Plasma cells are professional secretory cells, which function as cellular factories for immunoglobulin synthesis and secretion. Being the sole cell type responsible for antibody secretion they play an essential role in the immune response against a broad spectrum of pathogens.
