Plant tissue culture is a common laboratory technique for growing plant cells, tissues, and organs. This method allows researchers to select any part of a plant to grow. In plant tissue culture, researchers dissect plants by removing desired parts such as the leaf, embryo, shoot, or stem. Once these plant parts are removed, they are considered explants. These explants are transferred into a container with a semisolid, nutrient-rich media. The nutrient-rich medium serves as a soil substitute to support the growth and development of explants and includes hormones, agar or gelling agents, vitamins, sugar, and nutrients. When the explants are transferred into the medium, the jars will be sealed to prevent contamination. The jars are then moved into a growing chamber or room where conditions are favorable for the optimum growth of explants.
