Vedclass · Answer

(C) Plants have evolved various morphological and chemical defenses to protect themselves from herbivores.$1$. Morphological defenses include physical structures like thorns,spines,and prickles (e.g.,in Cactus and Acacia) that deter herbivores from grazing.$2$. Chemical defenses include the production of toxic substances like nicotine,caffeine,quinine,strychnine,and opium,which make the plant unpalatable or poisonous to the herbivore.$3$. Since spines are a morphological (mechanical) defense,option $C$ is the correct answer.

Which of the following is an important morphological defense mechanism in plants against herbivores?
