Question

F.C. Steward is associated with
A. Molecular biology
B. Genetics
C. Tissue culture
D. immunology

Answer 1

Hint:-
Scientists work, experiment and study on the different aspects of living organisms such as bacteria, fungi, plants and higher organisms. Several techniques developed by scientific observation and discoveries are economically useful to grow species with desirable characters. F.C. Steward was a well renowned botanist and plant physiologist.

Complete step-by-step solution
Frederick Campion Steward was born in London and was educated at the Heckmondwike Grammar School. He then moved to attend the prestigious University of Leeds. He gained his degree in the field of Biology from the university in the year and afterwards took up research in the Department of Botany.
He served several important and renowned institutions like the Cornell University and University of Chicago. He also served in the Ministry of Aircraft Production under British Government.
Prof. F.C. Steward was a world-renowned scientist in the field of plant physiology and he discovered as well as laid the foundation for plant tissue culture, genetic engineering and plant biotechnology. The most important scientific contribution contributed by him is that when he established that total regeneration of the plant could be done from a single cell. The idea of his discovery formed the very base of plant tissue culture. He also established that plant cuttings and shoots are not required to produce and propagate hybrid plants. But hybrids can be created through the individual cells of the plants as the cells contain all the necessary information regarding the regulation of the complete plant. Thus, his findings were of the opinion that the clones, mutations and the hybrids of the plants can be created in the laboratory instead of a lengthy process of cutting cultivation.
He was also successful in isolating the factors responsible for promoting and maintaining the cells of the plants from coconut milk. The coconut milk was found to promote cell growth during the embryonic and meristematic conditions.
Therefore, the correct option is option C.

Note:- F. C. Steward was an enthusiastic plant botanist and physiologist. He is the most prominent and pioneer researcher in the field of plant tissue culture. He showed that the plant cells possess the qualities of totipotency and can be grown in a laboratory. He was of the view that a single cell of a plant contains all the information needed to develop into a complete plant. Thus, he was a pioneer and was associated with the field of tissue culture especially plant tissue culture.
