Plant tissue culture is a practice of propagating plants under sterile conditions, often to produce clones of a plant. Here, new plants are grown by removing a tissue or separating cells from the growing tip of a plant. The cells are then placed in an artificial medium where they divide rapidly to form a small group of cells called callus. The callus is transferred to another medium containing hormones for growth and differentiation. The plantlets are then placed in the soil so that they can grow into mature plants. Using tissue culture, many plants can be grown from one parent under disease-free condition. This technique is commonly used for ornamental plants.
