Every Organism experiences growth and development. In several animals, for example frogs, their growth and development through process called metamorphosis.

1. is happen to change of body shape from egg until adult shape [ imago ].

2. Metamorphosis happen in insect and frog

3. Metamorphosis some trough chrysalis phase (pupa )/cocoon and some do not pass through chrysalis (phase pupa /kepompong).

Methamorphoses process of the frog :1. Ovulated eggs2. Embryo development phase (cell fission,

blastula stadium, gastrula stadium and tail begin to grow.

3. Hatching stadium4. Development during metamorphosis,

those are

Inners gill : its of 8 day old Gills cover : its of 12 day old Back leg : its of 2,5 months day Front leg : its of 3 months old Metamorphosis is finished, it is indicated

with tail disappearance The frog of 1 year old

1. imperfect /incomplete metamorphosis : if the shape in start of life as same as / similar with adult life.Imperfect metamorphose are as followEgg -- Young Animal (nymph) --adult animal/ imago

Ex: cockroach/kecoa, cricket, grasshopper, beetle, termites,

2. Perfect /complete Metamorphosis :If there are different shape between start of life & adult lifeCommonly happens in the insect group of homimetabola.The phase of perfect metamorphosis in insect are as follow :Eggs—Larva—chrysalis[cocoon,pupa]-adult /Imago

Ex: dragon fly, fly, bee, mosquito, butterfly , frog

Metamorphosis that through Phase of chrysalis (pupa )

The Metamorphosis happens in insect. The Metamorphosis' in insect is separated into two, those are Imperfect and perfect metamorphosis. Imperfect Metamorphosis commonly happens in the group of insect hemimetabola, the eggs hatch to be young animal and development to be adult animal

1. Metagenesis is change of generation from asexual generation to sexual generation. Phase generative & vegetative in their circle of life. Metagenesis happens in plant, particularly in moss plant / lumut and fern plant / paku-pakuan, and animal jelly fish( Aurelia sp , Obelia sp )

2. Metagenesis involves sexual cycle (gametophyte generation ) and asexual cycle ( Sporophyte generation)

1. internal factor a. Gene/genom b. Hormone

plant hormonea. Auxin : promote devision in the apical meristem (pucuk daun )b. Ethilen : promote the fruits maturationc. Absisat : supporting the realising old leaf & fall fruitsd. Geberulin : promote enlarge of frits

animal hormonea. Tiroksin : controle animal growth , in frog this hormon help to start of the

methamorphose process.b.somatomedin : controle bone growth.c. Edicson & juvenil : influence growth in larva & imago phase.

2. External factora. Foodb. Environment.
