Comparing Life Cycles - 3rd Grade Science

  1. What is the correct order of a flowering plant life cycle using these steps: seed, seedling, adult plant, flower, fruit?
    Seed → seedling → adult plant → flower → fruit (with seeds). Flowering plants reproduce through seeds in fruits.
  2. Identify the correct order for a flowering plant life cycle: seed, adult plant, seedling, flower.
    Seed, seedling, adult plant, flower. Correct sequence from seed to reproductive stage.
  3. Which option best compares a butterfly and a grasshopper life cycle: complete or incomplete metamorphosis?
    Butterfly: complete; grasshopper: incomplete. Butterflies have 4 stages; grasshoppers have 3.
  4. What is a nymph in insects with incomplete metamorphosis?
    A young stage that looks like a small adult but cannot reproduce. Gradually grows wings and reproductive parts.
  5. Which type of metamorphosis has three stages: egg, nymph, adult?
    Incomplete metamorphosis. Grasshoppers and dragonflies skip the pupa stage.
  6. What is the larva stage in many insects?
    A feeding and growing stage after the egg hatches. Larvae eat and grow before transforming.
  7. Which insect life cycle is complete metamorphosis: egg–larva–pupa–adult or egg–nymph–adult?
    Egg–larva–pupa–adult. Complete metamorphosis has four distinct stages including pupa.
  8. What is the correct order of a chicken life cycle?
    Egg → chick → adult chicken. Chickens grow directly without changing body form.
  9. Which frog stage breathes with gills: egg, tadpole, or adult frog?
    Tadpole. Gills allow tadpoles to breathe underwater.
  10. Which option best compares butterfly and grasshopper life cycles: both have pupa, or only butterfly has pupa?

    Nymph. Nymphs resemble miniature versions of adults.
  28. Which choice shows complete metamorphosis: egg→nymph→adult or egg→larva→pupa→adult?
    Egg → larva → pupa → adult. Pupa stage distinguishes complete metamorphosis.
  29. What does it mean when an organism has a life cycle with metamorphosis?
    It changes body form a lot as it grows. The organism's appearance transforms dramatically between stages.
  30. Which statement is true about plant life cycles: seeds come before flowers or flowers come before seeds?
