what is metamorphosis? how should i rite bout it?

Question

i need to know for my homework. wot i mean by how shud i rite it is : should i give any examples or any fing? if this helps, we r talking about greek myths, so it will probably have something to do with that.

Answer 1

Discuss some examples of metamorphosis in Greek myths - there are many examples. These sites should give you some ideas. Best of luck with it.

Answer 2

The best example I can give of metamorphosis is the change of a caterpillar into a butterfly. I'm not sure if it's specifically greek, or just mythology in general, but the rising of the phoenix from the ashes would be an example of metamorphosis.

Answer 3

The Metamorphosis of Narcissus (1937) is an oil on canvas painting by the Spanish surrealist Salvador Dalí. This painting is from Dalí's Paranoiac-critical period. According to Greek mythology, Narcissus fell in love with his own reflection in a pool. Unable to embrace the watery image, he pined away, and the gods immortalised him as a flower. Dali completed this painting in 1937 on his return to Paris after having had great success in the United States.

The painting shows Narcissus sitting in a pool, gazing down. Not far away there is a decaying stone figure which corresponds closely to him but is perceived quite differently as a hand holding up a bulb or egg from which a narcissus is growing. In the background, a group of naked figures can be seen, while a third narcissus like figure appears on the horizon.

A long poem was written by Dalí to accompany the painting. The Metamorphosis of Narcissus is currently on display at Tate Modern in London.

Answer 4

Talk about butterflies. That is the best known example. The process of change from larva into a crysalis then to emerge as a butterfly. This is an example from nature, but in terms of greek mythology there were many mammals and birds which underwent metamorphosis at the hands of their gods.

It is originally a Greek word. One story features Tithonus. One of the gods falls in love with him and promises to make him immortal but forgets to make him forever young. He shrinks and shrinks and turns into an insect. The exact details you will have to look for...

Metamorphosis
From Wikipedia, the free encyclopedia
Jump to: navigation, search
This article is about the biological process. For other uses, see Metamorphosis (disambiguation).
A Pieris rapae larva A new Pieris rapae pupa A ready-to-hatch Pieris rapae pupa A Pieris rapae adultMetamorphosis is a biological process by which an animal physically develops after birth or hatching, involving a conspicuous and relatively abrupt change in the animal's form or structure through cell growth and differentiation. Some insects, amphibians, molluscs, crustaceans, echinoderms and tunicates undergo metamorphosis, which is usually (but not always) accompanied by a change of habitat or behaviour.

Scientific usage of the term is exclusive, and is not applied to general aspects of growth, including rapid growth spurts. References to "metamorphosis" in mammals is imprecise and only colloquial.

[edit]
Stages
Metamorphosis usually proceeds in distinct stages, usually starting with larva or nymph, optionally passing through pupa, and ending as adult.

The immature stages of a species that metamorphises are usually called larva. But in the complex metamorphosis of many insect species, only the first stage is called a larva and sometimes even that bears a different name; the distinction depends on the nature of the metamorphosis.

The development of insect larva (like that of other arthropods) often also proceeds in stages called instars advanced by ecdysis (moulting).

Some insects hatch from an egg already having the general form of the adult, and the metamorphosis to adult form is usually marked mainly by the development of wings. This type of metamorphosis is called simple, gradual, or incomplete metamorphosis or hemimetabolism, and the young are called nymphs, or naiads when aquatic. It is often found in the order Mantodea, which is commonly known as praying mantis. They do not undergo stages like a caterpillar to a butterfly, but several stages where the nymph looks like a smaller-sized, wingless adult and ends the metamorphosis with fully developed wings.

By contrast, in complete or complex metamorphosis, or holometabolism the larva markedly differ from the adult. Insects with complete metamorphosis pass through a larval stage, then enter an inactive state called pupa (or chrysalis), and finally emerge as adults. A number of beetle species and Strepsiptera undergo hypermetamorphosis (a sequence of successively simpler larval forms) preceding pupation.

Whether the insect spends more time in its adult stage or in its juvenile form depends on the species. Notable examples of the latter are the mayfly, whose non-eating adult stage lives only one day, and the cicada, whose juvenile stage lives underground for as much as 17 years. These species have incomplete metamorphosis. Typically (though not exclusively), species in which the adult form outlives the juvenile form undergo complex metamorphosis.

Many observations have indicated that cell death plays a considerable role during physiological processes of multicellular organisms, particularly during embryogenesis and metamorphosis.

Comparative Lengths of Metamorphosis Species Egg Larva/Nymph Pupa Adult
Housefly 1 day 2 weeks 1 week 2 weeks
Ladybug 4 days 2 weeks 2 weeks 3-9 months
Monarch Butterfly 4 days 2 weeks 10 days 2-6 weeks
Periodical Cicada 1 month 13/17 years no such stage 2 months
Mayfly 1 month 3 years 1 day
Cockroach 1 month 3 months 9 months

Insect metamorphosis
All Apterygota and most Exopterygota insects are hemimetabolic, while all Endopterygota are holometabolic.

But a few Exopterygota -- such as Thysanoptera, Aleyrodidae and male Coccoidea -- undergo a metamorphosis more similar to the hemimetabolic one.

[edit]
Hormonal control
Insect growth and metamorphosis are controlled by hormones synthesized by endocrine glands near the front of the body.

Some cells of an insect's brain secrete a hormone that activates thoracic glands, which secrete a second hormone, usually Ecdysone (a steroid), that induces metamorphosis.

Moreover, the corpora allata produce the juvenile hormone, whose effect is to prevent the development of adult characteristics while allowing ecdysis. Therefore, the insect is subject to a series of moult, controlled by Ecdysone, until the production of juvenile hormone ceases and metamorphosis occurs.
