Metamorphosis Perfect and Imperfect
Metamorphosis is a biological process in animal development that involves changing the physical structure after birth or hatching (hatching). Metamorphosis is two complete metamorphosis and incomplete metamorphosis (Holometabola and Heterometabola). Here's a brief explanation of metamorphosis and incomplete, especially in insects.
Perfect Metamorphosis (Holometabola)
In complete metamorphosis, insects in the life cycle experiencing striking changes in the outside design and various organs of the stage. Insect larvae and adult forms of these groups no resemblance In complete metamorphosis. Changes occurring form are as follows:
Eggs -larva - pupa (chrysalis) - Imago (adult)
The eggs hatch into larvae. Larvae generally experience molting four times forming stage larvae stage larvae of one to four. In the larval stage. generally very active insect meal.
Just look at the larval stage of butterflies are caterpillars, which feed on the leaves very active. 3-stage larvae pupa stage four turns of the traffic system. In the pupa stage. inactive insect eating (fasting period). but the metabolic process remains ongoing. After experiencing growth and cell division, differentiation and organogenesis. then the pupa will turn into an adult insect (Imago). Besides metamorphosis, repetition of the process as well as on growth and embryonic development hlngga larvae eventually turn into the adult form.
So what caused the changes in the metamorphosis of insects? What happens to the body in the form of insect larvae that had been filled with food after metamorphosis? When an insect pupa form, occurs ProRes histolysis or destruction from within the network or the insect's body by oneself. Fluid that was previously used to digest the food used for the histolysis. In addition, cells called histoblast larvae will reorder the insect's body becomes an adult body use the nutrients in food and the larvae are ingested into the liquid in the pupa. The metamorphosis of insects in the pupa must not leak and a disruption means to interrupt the implementation of the histogenesis or the rearrangements that occur.
Examples of insects that undergo complete metamorphosis, among others butterflies, flies, mosquitoes. bees and beetles.

Metamorphosis is not perfect (Heterometabola)
In incomplete metamorphosis, insects undergo metamorphosis from egg to adult is not prominent in the life cycle. Pradewasanya larval form or shape is called a nymph. Nimfa has similarities with the adult form (imago), except the reproductive organs and wings. Reproductive organs and wings on nymphs undeveloped. Only after the turn into an adult insect. Developing reproductive organs and insects can reproduce. In incomplete metamorphosis is not formed pupa stage. In sempurna.perubahan metamorphosis occurring form are as follows: Eggs - nymphs - imago (adult)
Examples of insect metamorphosis sempurnaa not include grasshoppers, cockroaches (cockroach), and the Crickets.
Thus a brief explanation about the metamorphosis and incomplete, I hope you learn also related posts below.
