Transcript

  • 1. Complete and Incomplete Metamorphosis Let’s look at the difference!
  • 2. What is metamorphosis?
    • Metamorphosis refers to the way that certain organisms develop, grow, and change form.
    • Metamorphosis actually means "change".
  • 3. Two Types of Metamorphosis
    • INCOMPLETE METAMORPHOSIS - has THREE stages
    • COMPLETE METAMORPHOSIS -
    • has FOUR stages.
  • 4. INCOMPLETE METAMORPHOSIS
    • Let’s take a closer look
    • at each stage!
  • 5. 3 STAGES OF INCOMPLETE METAMORPHOSIS
    • Egg
    • Nymph
    • Adult
  • 6.
    • EGG
    • A female insect lays eggs. These eggs are often covered by an egg case which protects the eggs and holds them together.
  • 7.
    • 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.
  • 8.
    • ADULT
    • The insects stop molting when they reach their adult size. By this time, they have also grown wings.
  • 9. COMPLETE METAMORPHOSIS
    • Let’s take a closer look
    • at each stage!
  • 10. 4 STAGES OF COMPLETE METAMORPHOSIS
    • Egg
    • Larva
    • Pupa
    • Adult
  • 11.
    • EGG
    • The female lays eggs.
  • 12.
    • 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.
  • 13.
    • 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.
  • 14.
    • ADULT
    • Inside the cocoon, the larvae change into adults. After a period of time, the adult breaks out of the cocoon.
  • 15. 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.
  • 16. Let’s see what we know!
    • Let’s take Professor
    • Know-It-All’s Quiz
    • and see what we have
    • learned!
