60. What is meant by 'Organ culture’?

• A. Maintenance alive of a whole organ, after removal from the organism by partial immersion in a nutrient fluid.
• B. Introduction of a new organ in an animal body with a view to create genetic mutation in the progenies of that animal.
• C. Cultivation of organs in a laboratory through the synthesis of tissues.
• D. The aspects of culture in community which are mainly dedicated by the need of a specified organ of the human body.

Answer 1

The correct option is A Maintenance alive of a whole organ, after removal from the organism by partial immersion in a nutrient fluid.

In biological research, tissue culture refers to a method in which fragments of a tissue (plant or animal tissue) are introduced into a new, artificial environment, where they continue to function or grow. While fragments of a tissue are often used, it is important to note that entire organs are also used for tissue culture purposes. Organ culture is a type of tissue culture that involves isolating an organ for in vitro growth. Here, any organ plant can be used as an explant for the culture process (Shoot, root, leaf, and flower).
With organ culture, or as is with their various tissue components, the method is used for preserve their structure or functions, which allows the organ to still resemble and retain the characteristics they would have in vivo. Here, new growth (differentiated structures) continues given that the organ retains its physiological features. As such, an organ helps provide information on patterns of growth, differentiation as well as development.
