Life Cycle of a Frog
Eggs
Tadpole
Tadpole
(back legs form)
Froglet
Adult Frog
10 days
At 10 days the tadpole leaves the egg.
At 8 weeks the back legs have formed.At 12-14 weeks the tail begins to disappear.It takes about 3 years for the frog to reach adult hood.8Slide9

Comparing Tadpoles to Frogs
Tadpoles
Frogs
Tadpoles have gills.
They lose their gills and breathe with lungs.
Tadpoles have tails.
They lose their tails when they become frogs.
Tadpoles cannot reproduce.
Frogs can reproduce.
Tadpoles cannot live on land.Frogs can live on land.10Slide11
Life Cycle of a Bean Plant
1. Seed is planted
2. Seedling grows roots
3. Plant pushes above the soil; leaves begin to form
4. Plant is fully grown; bean pod begins to growSlide12
Check your Understanding
What is the major difference between a complete metamorphosis and an incomplete metamorphosis?
What does this illustration show?
Complete metamorphosis has 4 stages and the hatched insect does not look anything like the adult it will become; incomplete metamorphosis is when the newly hatched insect looks like a smaller version of the adult.
The life cycle of a butterfly – complete metamorphosisSlide13
3. Describe the life cycle shown in this illustration.
What type of life cycle is described below?
Egg
nymph adult
The acorn is
the seed that gets planted in the ground. The seed grows into a sapling plant which then becomes the oak tree. The oak tree then drops
acorns to the ground and the cycle begins again.
Incomplete metamorphosis – only 3 stages
