Question

Plants can be made disease-resistant through
A. Colchicine treatment
B. X-ray treatment
C. Breeding with wild relatives
D. Hormone treatment

Answer 1

Hint: The word disease resistance means the ability to reduce or prevent the presence of disease in a host. Various external factors and genetic combinations of plants are responsible for plants to get infected by the disease. Pathogens attack the plant host to infect the plants.

Complete answer: The disease resistance in plants protects the plants from pathogens by forming structures and chemicals and by inducing infection response to the immune system. The plant's disease resistance makes the plant immunity strong and reduces the growth of pathogens on or in the plant.
-Colchicine is a type of drug which is used for the treatment of gout and Bechet’s disease. Gout is also used as a medication for the prevention of pericarditis and familial Mediterranean Fever.
-Radiography is a diagnostic technique in which radiations are allowed to penetrate a patient's body to get a visual picture of inside body parts. Normally it is used to detect fractures in bones.
-Wild relatives of plants are genetically related to cultivated crops. Such plants are disease resistant with drought tolerance or pest resistance.
-Hormone treatment refers to injecting external hormones into the body. It can be taken in the form of injections or consumed orally as a pill.
So, option C is the correct option.

Note: Disease resistance and disease tolerance both are different. Disease tolerance means the ability of the host to tolerate or limit the impact of the disease on host health. The breeding of plants with wild relatives produces hybrid plants that are immune to infections and disease.
