Plant Defense Responses: Physical, Chemical, and Mechanical Adaptations

The video explores how plants defend themselves against pathogens and herbivores through physical, chemical, and mechanical defenses. Physical defenses include barriers like cell walls and waxy cuticles. Chemical defenses involve antibacterial chemicals and poisons. Mechanical adaptations include thorns, hairs, and mimicry. The video concludes with a recap of these plant defense mechanisms.

What is the significance of thorns and hairs in mechanical adaptations of plants?
