Plants Eating Organisms Mechanical Defences Pathogens Adapted Thorns

Plants employ mechanical defenses like thorns, hairs, leaf movement, and mimicry to deter consumption by animals and insects.

Plants have mechanical defenses like thorns, hairs, drooping leaves, and mimicry to deter animals and insects from eating them.

Front What are the mechanical defences that plants have against pathogens?
Back
  • Some plants have adapted to have thorns and hairs to stop animals from touching and eating them
  • Other plants have leaves that droop or curl when something touches them - prevent themselves from being eaten by knocking insects off themselves 
  • Some plants mimic other organisms which tricks the organisms into not eating them
