  1. Animals and InsectsMetamorphosis Incomplete Metamorphosis – 3 stages of development Egg nymph adult Examples: cockroaches, grasshoppers, dragonflies

  2. Complete Metamorphosis – 4 stages of development Egg larva pupa adult Examples: meal worms, butterflies, ladybugs,

  3. Vocabulary – Molting – When an insect sheds their outer skeleton Direct Development – When organisms grow larger but keep their same body shape

  4. Plant Life Cycle (comparisons) Life Cycle – distinct stages that make up an organism’s life. Plants – seed germination seedling (sprout) --takes in WATER thru roots/producesFOODin its leaves/passes food & H2O in stem-- full grown plant with flower (flowering plants – make seeds) some flowers produce fruit (that fruit holds the seeds of the plant). --Flowers/fruits/cones= seeds for REPRODUCTION-- • Pollination occurs in the flowers • The seed is formed after pollination • This is when the cycle begins again

  5. Vocabulary – Molting – When an insect sheds their outer skeleton Direct Development – When organisms grow larger but keep their same body shape
