Vocabulary

Cycle- A

series of repeating events that usually lead back to a

starting point.Metamorphosis- A physical or structural change (transformation).

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
