Plants, though rooted and seemingly passive, have evolved an array of sophisticated defenses to survive in a world full of threats. From chemical warfare to physical barriers, these green warriors have developed ingenious ways to fend off herbivores, pathogens, and environmental stresses. Ready to challenge your understanding of the botanical battleground? Let’s dive into the intricate world of plant defenses and see how much you know!
