1 Life Cycles

2 Objective: Plants and animals have life cycles that include the beginning of life, growth and development, reproduction and death. The details of a life cycle are different for different organisms.

3 Let’s see what you already know about life cycles…

4 Word Bank adult death tadpole eggs pupa larva egg nymph hatching 1. Most animals come from ______________. 2. When an animal breaks out of an egg, that is called ________________. 3. What are the three stages of growth of a grasshopper? A.___________________ B.___________________ C._______________ 4. Name the stages of butterfly growth. A.___________________ B.___________________ C.___________________ D.___________________ 5. The second stage in the life cycle of a frog is called a _______________. 6. The final stage in the life cycle of all animals is _________________.

5 Vocabulary life cycle metamorphosis stages of the life cycle pupa larva egg adult chrysalis nymph molting maturity tadpole

6 Essential Vocabulary Life cycle – the stages a plant or animal goes through from egg to adult Metamorphosis – the process of change during the life cycle Simple metamorphosis – the process of change during the life cycle where the young resembles the adult

7 Complete metamorphosis – the young does not look like the adult Life cycle stages –Birth –Growth/change –Maturity –Death

8 3 Phase Insect Life Cycle

9 Simple Metamorphosis Insects Cockroaches Grasshoppers Dragonflies

10 4 Phase Insect Life Cycle

11 Complete Metamorphosis Insects Beetles Butterflies/moths Flies Ants, wasps, bees fleas

12 Identify the following life cycles as - simple (3 phases) - complete (4 phases)

13 Life Cycle of a Butterfly

14 Dragonfly Life Cycle

15 Mosquito Life Cycle

16 Grasshopper Life Cycle

17 Now, let’s try that test again and see what you have learned!
