Comparing Life Cycles
4.10C – explore, illustrate, and compare life cycles in living organisms
5.10C – describe the differences between complete and incomplete metamorphosis of insectsSlide2
series of repeating events that usually lead back to a
starting point.Metamorphosis- A physical or structural change (transformation).

Life Cycle of a Frog
(back legs form)
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
Can you label
TadpoleTadpole with legsFrogletAdult FrogSlide10
Comparing Tadpoles to 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?
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

LTEC 4100 .003. Fall 2010. Learning Objectives. Students will understand the life cycle of butterflies. Students will be able to label and draw the life cycle of butterflies. Students will be able to label the parts of a butterfly (wings, abdomen, head, antanne).
Compare the life cycles of different kinds of animals.. Vocabulary . Adult. -the stage of an animal’s life cycle when it reproduces. . Egg. -a structure containing food that young animals need in order to grow. .
Objective(s): I can. List the characteristics all living things share.. Explain where living things come from.. Identify what all living things need to survive.. Key terms. Organism. Cell. Unicellular.
Think!. What is a cycle? What are some cycles you know about in the world we live in?. What is a cycle?. A single complete execution or a periodically repeated phenomenon.. What does that mean?. Single – it happens one time.
Section 1 – the world of biology. Section 2 – themes in biology. Section 3 – the study of biology. Section 1 – the world of biology objectives. Relate the relevance of biology to a person’s daily life..
