Unit 4, Lesson 6
A
series of distinct growth
stages in an animal’s life cycle
that are different from one
another.
A
series of four distinct growth
stages in an animal’s life cycle.
 Egg,
larva, pupa, adult
 An
immature stage in complete
metamorphosis where the
organism does not resemble the
adult

A non-feeding stage in complete
metamorphosis in which a hard, case-like
cocoon surround the organism
A
series of three growth stages
that occur gradually
 Egg,
nymph, adult
A
stage of metamorphosis
where the organism is similar
to an adult form but is smaller
 Larva
 The
organism gets bigger but
keeps the same basic shape and
form

Complete metamorphosis has 4 distinct
stages, while the incomplete metamorphosis
has only 3 distinct stages.
 Most
tadpoles are
herbivores, or plant eaters
Frog eggs are laid in the water. If
tadpoles hatched with lungs rather
than gills, they would not be able to
breathe.
 Tadpoles are completely aquatic for
the first part of their lives

 It
moves onto land
 Breathes air
 Begins meat eating diet
 The
shell keeps the embryo from
drying out.
 The
yolk provides food for the
developing embryo.
 It
is protected by a jellylike layer
that surrounds the egg




Butterflies
Moths
Flies
Beetles



Grasshoppers
Termites
Bedbugs
 In
incomplete metamorphosis, the
nymph stage is the same as the
larva stage in a complete
metamorphosis, and the pupa
stage is skipped.

Grasshoppers have an exoskeleton
 Amphibians
go through
metamorphosis, but other
vertebrate do not.
 Animals
have different eggs
depending on their structures
and the environments in which
they live.
 Monotremes
are the only
mammals that lay eggs.
