The example of a plant that can survive pest infestations with minimal damage demonstrates host resistance effectively. Host resistance refers to an organism's inherent ability to withstand or fend off pests or diseases with little adverse effect. This concept is crucial in agricultural and ecological contexts, as it highlights how certain plants have evolved mechanisms—such as physical barriers, chemical defenses, or other traits—that enable them to endure or combat pest attacks.

In this case, the plant’s ability to withstand infestations means it has developed characteristics or adaptations that enhance its survival in the face of potential threats, exemplifying the principle of host resistance. Understanding such mechanisms helps in developing pest management strategies that favor crops or species with natural resilience, reducing the reliance on chemical control methods.
