Although plants cannot move freely to escape plant-eaters, they have adaptations to defend themselves – using both chemicals and physical structures such as spines, to deter animals from feeding on them.
Nectaries
Some plants recruit insect bodyguards by offering them food in the form of sweet nectar produced by nectaries near their leaves. In return for the sweet treat, these insects protect the plant from other plant-eaters.
Plant mimicry
Animals are not the only organisms that appear to resemble other organisms. Some plants have structures that make them appear unappetizing to plant-eaters such as resembling poop or pebbles!
