Which property of immunity exists when the plasma membrane of each T cell and B cell has receptors that will bind only one particular type of antigen, ignoring all other types of antigens?

specificity

Explanation:

Adaptive immunity or specific immunity refers to the defense mechanisms of the body against specific invading agents. Adaptive immunity exhibits specificity and memory, the features not exhibited by innate immunity. The specificity of immune system serves the ability of the immune cells to identify specific pathogens or foreign molecules and produce an immune response against them.

It also involves distinguishing self from nonself molecules. The B cells and T cells have specific receptors that recognize and bind to specific antigens only and produce an immune response against them only while not responding to the other antigens.
