complete and incomplete metamorphosis

Complete and Incomplete Metamorphosis

Let’s look at the difference!

what is metamorphosis
What is metamorphosis?
  • Metamorphosis refers to the way that certain organisms develop, grow, and change form.
  • Metamorphosis actually means "change".
two types of metamorphosis
Two Types of Metamorphosis
  • INCOMPLETE METAMORPHOSIS - has THREE stages
  • COMPLETE METAMORPHOSIS -

has FOUR stages.

incomplete metamorphosis
INCOMPLETE METAMORPHOSIS

Let’s take a closer look

at each stage!

slide6
EGG
  • A female insect lays eggs. These eggs are often covered by an egg case which protects the eggs and holds them together.
slide7
NYMPH
  • The eggs hatch into nymphs.
  • Nymphs looks like small adults, but usually don\'t have wings.
  • Insect nymphs eat the same food that the adult insect eats.
  • Nymphs shed or molt their exoskeletons (outer casings made up of a hard substance called chitin) and replace them with larger ones several times as they grow.
  • Most nymphs molt 4-8 times.
slide8
ADULT
  • The insects stop molting when they reach their adult size. By this time, they have also grown wings.
complete metamorphosis
COMPLETE METAMORPHOSIS

Let’s take a closer look

at each stage!

slide11
EGG
  • The female lays eggs.
slide12
LARVA
  • Larva hatch from the eggs. They do not look like adult insects. They usually have a worm-like shape.
  • Caterpillars, maggots, and grubs are all just the larval stages of insects. Larvae molt their skin several times and they grow slightly larger.
slide13
PUPA
  • Larva make cocoons around themselves.
  • Larva don\'t eat while they\'re inside their cocoons.
  • Their bodies develop into an adult shape with wings, legs, internal organs, etc.
  • This change takes anywhere from 4 days to many months.
slide14
ADULT
  • Inside the cocoon, the larvae change into adults. After a period of time, the adult breaks out of the cocoon.
what about frogs
WHAT ABOUT FROGS?
  • Frogs undergo a different type of COMPLETE METAMORPHOSIS.
  • From the egg emerges a tadpole, which lives in the water, breathes with gills, and has a tail.
  • As the tadpole grows, lungs and legs form, and the gills and tail are absorbed into the body.
  • Finally, the animal leaves the water and lives mainly on land, as a frog.
