Question

Quizplus · Accepted Answer

Adaptive immunity is based upon antigen-specific recognition, meaning that the immune system is able to recognize and respond to specific pathogens by producing antibodies or immune cells that target those particular pathogens. This is in contrast to innate immunity, which responds to more general traits common to groups of pathogens. Maternal provision of antibodies to offspring can provide temporary protection, but it is not the basis of adaptive immunity. Plants being exposed to new pathogens is not relevant to adaptive immunity in animals. Having exhausted all options for innate immunity responses is not a valid explanation for adaptive immunity.
