Document Summary
In the plant body: target for heterotrophs through predation/parasitism. Threat defense: internal: physiological, chemical, external: Threat recognition defense: all this implies costs and trade-offs, same process in predator arms race. Plants have evolved mechanisms to protect themselves from infection by pathogens, which include viruses, bacteria, fungi, worms, and even parasitic plants. Plants use chemical, mechanical, and ecological defenses to protect themselves from being eaten by herbivores. The production of defenses is costly, resulting in trade- offs between protection and growth. Interactions among plants, pathogens, and herbivores contribute to the origin and maintenance of plant diversity. Core concept 1: plants have evolved mechanisms to protect themselves from infection by pathogens, which include viruses, bacteria, fungi, worms, and even parasitic plants. Entry through scratches, fool guard cells to open gate, break down door and sneak in. Use vascular tissue to move around inside.
