Quizplus · Accepted Answer

Plants do not have an adaptive immune system like animals, so they do not produce antibodies, CTL (Cytotoxic T Lymphocytes), or have CD4 cells. Instead, they rely on innate defense mechanisms such as the production of reactive oxygen species (ROS) to combat microbial pathogens. ROS can directly damage pathogens or signal for further defense responses in the plant.
