Plant Defence

Plants have evolved a range of defence strategies to protect themselves against predators. These strategies include physical defences such as thorns, spines, and trichomes; chemical defences such as allelopathy and biocontrol; and morphological defences such as changes in leaf size, shape, or texture. These defences work together to make plants difficult to consume and to reduce the likelihood of predation. Plants also produce secondary metabolites, such as toxins and repellents, which can deter predators or even kill them. These compounds can also help plants resist pathogens and environmental stressors. Plants also use their roots to take up beneficial minerals and water, while using their leaves to absorb light and carbon dioxide. Together, these strategies help plants survive in their environment.
