Suggest some of the features of plants that will prevent insect and pest infestation.

(N/A) The morphological and biochemical features of plants that provide resistance against insect and pest infestation include:
$(i)$ Increasing hair growth on aerial parts of plants (hairy leaves),which prevents insect attachment and feeding.
$(ii)$ Rendering the flowers nectar-less,which discourages pollinators or insects that feed on nectar.
$(iii)$ Enabling plants to secrete insect-killing chemicals (toxins),such as the production of aspartic acid,low nitrogen,and low sugar content in maize,which makes them resistant to stem borers.
