Plants Use Pungent-Smelling Chemicals to Protect Their Next-Generation From Predators

However, after millions of years of evolution, they have in-built a defensive system to ensure their survival for the next generation. A recent study by the University of Copenhagen, Denmark , proposed that plants use substances that taste similar to wasabi and mustard sauce that stimulate a burning sensation in their predators' mouths, thereby preventing themselves from getting eaten up. Instead of serving plants as food, these pungent-smelling chemicals repel insects and herbivores to defend them. Glucosinolates are naturally occurring substances in plants that play an important role in their defensive mechanisms. When herbivores start eating plant leaves, the plant tissues are crushed, and an enzyme is released called Myrosinase. This enzyme gets mixed with glucosinolates to produce toxic metabolites that inhibit most insects to
