What is meant by plant chemical defences?

Plant chemical defences are chemicals made by plants to protect them from disease and from being eaten.

Chemical defences are substances the plant makes, while physical defences are tough structures that act as barriers.

They are chemicals that kill or slow down microbes such as bacteria and fungi.

They reduce the number of pathogens, so infection cannot spread through the plant.

A toxin is a poison made by the plant that harms or kills herbivores or microbes.

Animals dislike the taste, so they stop eating the plant’s leaves or other parts.

Aspirin, a painkiller, was first made from a chemical in willow bark.

They help crops resist diseases and pests, so more healthy food can be grown.
