  • 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
  • Lets see what you already know about life cycles

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 _________________.

Vocabulary
  • life cycle
  • metamorphosis
  • stages of the life cycle
  • pupa
  • larva
  • egg
  • adult
  • chrysalis

  • Growth/change
  • Maturity
  • Death

3 Phase Insect Life Cycle

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

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