Plant Cell Culture What is meant by 'Organ culture' ? Cultivation of organs in a laboratory through the synthesis of tissues Maintenance alive of a whole organ, after removal from the organism by partial immersion in a nutrient fluid Introduction of a new organ in an animal body with a view to create genetic mutation in the progenies of that animal The aspects of culture in community which are mainly dedicated by the need of a specified organ of the human body Cultivation of organs in a laboratory through the synthesis of tissues Maintenance alive of a whole organ, after removal from the organism by partial immersion in a nutrient fluid Introduction of a new organ in an animal body with a view to create genetic mutation in the progenies of that animal The aspects of culture in community which are mainly dedicated by the need of a specified organ of the human body ANSWER DOWNLOAD EXAMIANS APP
