Which of these is NOT a plant defence mechanism?
Callose deposition at plasmodesmata and cell walls is an example of which type of defence?
The hypersensitive response in plants leads to rapid cell death around the infection site. What is the main benefit of this response?
Which plant defence would most directly reduce the survival of a fungal spore trying to germinate on a leaf surface?
Which molecule often acts as a mobile signal to alert distant parts of the plant after local infection?
What is the primary advantage of induced (triggered) defenses over constitutive (always-present) defenses?
What is the main role of stomatal closure during pathogen attack or drought?
Which of the following best describes systemic acquired resistance (SAR)?
Which plant response is chemical and acts directly to inhibit pathogen growth?
How do some plants use volatile organic compounds (VOCs) when attacked by herbivores or pathogens?
