Plant Defence

Plants have evolved a range of defence mechanisms to protect them from predators. These strategies include physical defences like thorns, spines, and trichomes, as well as chemical defences like allelopathy and biocontrol. Morphological defences like changes in leaf size, shape, or texture are also included. In combination, these defences make plants difficult to consume and less likely to be attacked by predators. Plants produce poisons and repellents as secondary metabolites, which can hurt or even kill predators. These chemicals can also help plants fend against illnesses and environmental hazards. Additionally, plants absorb light and carbon dioxide through their leaves while taking in water and necessary nutrients through their roots. Together, these strategies help plants survive in their environment.
