Function : noun
Date : 1533
1. change in form or structure; result of a complete change in appearance; change or succession of changes in an organism which enables it to survive in a new environment (Zoology); change in form or function of a plant during its development (Botany). metamorphosis\met`a*mor"pho*sis\ , n.; pl. metamorphoses (#). [l., fr. gr. , fr. to be transformed; beyond, over + form.].
2. change of form, or structure; transformation.
3. (biol.) a change in the form or function of a living organism, by a natural process of growth or development; as, the metamorphosis of the yolk into the embryo, of a tadpole into a frog, or of a bud into a blossom. especially, that form of sexual reproduction in which an embryo undergoes a series of marked changes of external form, as the chrysalis stage, pupa stage, etc., in insects. in these intermediate stages sexual reproduction is usually impossible, but they ultimately pass into final and sexually developed forms, from the union of which organisms are produced which pass through the same cycle of changes. see:
transformation.
4. (physiol.) the change of material of one kind into another through the agency of the living organism; metabolism.
5. Change of form, or structure; transformation.
6. A change in the form or function of a living organism, by a natural process of growth or development; as, the metamorphosis of the yolk into the embryo, of a tadpole into a frog, or of a bud into a blossom.

9. See Transformation.
10. The change of material of one kind into another through the agency of the living organism; metabolism. a complete change of physical form or substance especially as by magic or witchcraft the marked and rapid transformation of a larva into an adult that occurs in some animals.
11. When a metamorphosis occurs, a person or thing develops and changes into something completely different. his metamorphosis from a republican to a democrat = transformation. In biology, any striking developmental change of an animal's form or structure, accompanied by physiological, biochemical, and behavioral changes. The best-known examples occur among insects, which may exhibit complete or incomplete metamorphosis (see:
nymph). The complete metamorphosis of butterflies, moths, and some other insects involves four stages: egg, larva (caterpillar), pupa (chrysalis or cocoon), and adult. The change from tadpole to frog is an example of metamorphosis among amphibians; some echinoderms, crustaceans, mollusks, and tunicates also undergo metamorphosis.
