The part of the plant that is used for tissue culture is called explant. The stems, roots, leaves, floral parts, meristem, etc., are used as explants. These are taken out from the plant and grown in an artificial medium, under sterile conditions. The cells of these parts have the capacity to generate a whole plant. This property of the cells is called totipotency.
