    Morphallaxis is a mechanism of regeneration involving reorganization of body cells. In epimorphosis new cells proliferate from the surface of the wound to form the missing structure. In accretionary growth some specialized cells retain the ability to divide and produce new cells to replace the worn-out.

    Cloning is a technique by which genetically same individuals can be produced without including any sexual reproduction eg. Dolly sheep. The term clone is derived from źėłķ, the Greek word for “twig”, refering to the process, whereby a new plant can be created from a twig.

    Agave species are popular ornamental plants. Each rosette is monocarpic and grows slowly to flower only once. During flowering a tall stem or “mast” grows from the center of the leaf rosette and bears a large number of short tubular flowers. After development of fruit the original plant dies, but suckers are frequently produced from the base of the stem which become new plants. It is a common misconception that Agaves are cactus.

    Apomixis (asexual seed formation) is the result of a plant gaining the ability to bypass the most fundamental aspects of sexual reproduction: meiosis and fertilization. Without the need for male fertilization, the resulting seed germinates a plant that develops as a maternal clone.
