What Are Some Histological Features That Aid in Plant Defense?
Several histological features play a crucial role in plant defense:
Trichomes: These hair-like structures can deter herbivores physically or by producing toxic substances. Sclerenchyma: This tissue provides mechanical support and protection with its thickened cell walls, making it difficult for herbivores to chew through. Cuticle: A waxy layer on the surface of leaves and stems that acts as a barrier to pests and pathogens. Lignin: Found in cell walls, lignin adds rigidity and resistance to degradation by herbivores. Idioblasts: Specialized cells that store defensive chemicals like calcium oxalate crystals, which can deter herbivory.
