Tissue culture is the growth of tissues or cells in an artificial medium separate from the organism. This is typically facilitated via use of a liquid, semi-solid, or solid growth medium, such as broth or agar. Tissue culture commonly refers to the culture of animal cells and tissues, with the more specific term plant tissue culture being used for plants. The term "tissue culture" was coined by American pathologist Montrose Thomas Burrows. In modern days, plant tissue culture is used to maintain or grow plant cells, tissues or organs. This technique is widely used to produce clones of different plants, also known as micropropagation. At Green Sun Inc., we use this technique to propagate newer fruit varieties so they can be widely distributed and commercialized by local farmers.
