what is an undefferentiated callus in plants

Answer 1

An undifferentiated callus in plants refers to a mass of rapidly dividing, unorganized, and non-specialized cells that forms at a wound site or in tissue culture. Callus formation is a natural response of plants to injury or stress, and it serves as a protective barrier or a potential source of cells for tissue regeneration. Undifferentiated callus is characterized by its lack of specialized structures or functions, such as roots, shoots, or leaves. However, under appropriate conditions, the undifferentiated callus cells have the potential to differentiate and develop into various specialized tissues or organs, such as roots, shoots, or embryonic structures.
