Question

Quizplus · Accepted Answer

Memory cells are specialized immune cells that retain the ability to recognize specific pathogens they have encountered before. When a pathogen re-enters the body, memory cells quickly recognize it and divide to produce plasma cells, which secrete antibodies to fight the invading pathogen. Therefore, choice D is the correct answer. Choices A and B are incorrect because memory cells do not secrete antibodies immediately when they are formed and they are not supporting cells. Choice C is incorrect because memory cells are a type of B cell, not a type of T cell.
