Morphallaxis is always a great word to know.
So is asexual. Does it mean:
having no sexual organs; independent of sexual processes; not involving the union of male and female germ cells
a microscopic structure containing nuclear and cytoplasmic material enclosed by a semipermeable membrane, the basic structural unit of all organisms

morphallaxis

a process of tissue reorganization observed in many lower animals following severe injury, such as bisection of the animal, and involving the breakdown and reformation of cells, movement of organs, and redifferentiation of tissues. The result is usually a smaller but complete individual, derived entirely from the tissues of part of the original animal.
