Document Summary
23. 1) innate immunity: is activated by infection; b) depends on previous exposure to a specific pathogen; c) depends on antibodies; d) occurs only in vertebrate animals; e) occurs only in land plants. 23. 2) adaptive immunity depends on: traits common to groups of pathogens; b) pathogen-specific recognition; c) maternal provisioning of antibodies to the developing embryo; d) plants being exposed to new pathogens; e) having exhausted all innate immune responses. 23. 3) antigens are: blood proteins that cause foreign cells to clump; b) proteins embedded in b cell membranes; c) epitopes; d) foreign molecules that trigger antibody production; e) proteins produced during an inflammatory response. 23. 4) one way to prevent pathogen entry would be to have a continuous outer. heal the wound; d) block entry of pathogens through the wound; e) induce the production of phytoalexins. 23. 8) plant immune responses are typically induced, rather than constitutively engaged. What is the benefit of this: 1 of 12.
