Question

Professor K.C. Mehta is known for his contribution in the field of:
A)Bryology
B)Plant physiology
C)Virology
D)Plant pathology

Answer 1

Hint: Professor K.C. Mehta is an eminent scientist of India. Who is known for his great contribution of pathogenic disease in plant species. He worked on recurrence of rust in India, black rust of cereals in Cambridge University.

Complete answer:
Plants are the primary producers of energy and provide food for living organisms directly or indirectly. Human beings are majorly dependent on plants for their food resources. Food products obtained from plants are cereals, maize, rice, wheat, fruits, etc.

We cultivate plants to obtain their products and to obtain higher yield and better quality. But we need to protect our crops from pathogenic organisms like bacteria, fungal, viruses, protozoa, etc. And other insects which are mites, vertebrates or pests.

The branch of science which is involved in study of pathogenic disease is known as plant pathology. And Professor K.C. Mehta, is very much famous for his contribution in plant pathology. He carried out his research in the field of rusting of plants which is caused by fungus and it changes colour of plant leaves from green to brown, red or orange.

Hence, the correct answer is option (D)

Note: To protect these plants researchers have created many chemicals and biological compounds which control these pathogens and do not harm the crop or its production. Professor K.C. Mehta, worked on development of strategies by which we can protect our crops and plants in a better way. He is from India and worked in India as well as in Cambridge University to get better results.
