TED-ED: The amazing ways plants defend themselves - Valentin Hammoudi

Plants face numerous threats from various herbivores and pathogens. To combat these, they employ a range of defenses, including physical barriers like bark and thorns, and chemical defenses such as irritants and toxins. Plants also have an immune system where each cell can detect and respond to invaders. They communicate with other plants and recruit allies like parasitic wasps to fend off attackers. Despite being immobile, plants have evolved complex strategies to survive and deter predators.
