Plants vs. Insects, Episode 2: Plants Fight Back with PHYSICAL Defenses

This is the second episode in our series on plants and insect herbivores. In this episode, we dive into the physical and structural defenses plants use to deter herbivores. From trichomes and thorns to waxy leaves and egg mimicry, we explore how plants protect themselves from insect attacks. With fascinating examples like tomato plants’ sticky defenses, cacti spines, and grass silica barriers, we'll also begin to uncover the evolutionary adaptations herbivores have developed to overcome these defenses.
