  1. 4. The essential condition of right temperature required for a tiny baby plant to begin breaking out of its protective coat.
  2. 5. The non-feeding resting stage of a mosquito or mealworm beetle where it undergoes major structural changes inside a cocoon.
  3. 7. A very young plant that has developed its first roots and shoot but still relies on its temporary food store.
  4. 8. A life cycle with three distinct phases of development, which is observed in chickens, frogs, and cockroaches.
  5. 9. The process where a baby plant breaks out of its protective outer layer and begins to grow under the right conditions.
  6. 10. The very first stage of development for a chicken, frog, or butterfly before it hatches into the next phase.
  7. 13. The young, active eating stage of a butterfly or beetle that looks completely different from its parent.
  8. 14. The final fully developed stage of an organism where it is mature enough to reproduce and lay eggs.
  9. 15. The green structures that appear later and capture sunlight to make food for the plant once the food store runs out.
  10. 17. The young stage of a cockroach or dragonfly that looks similar to its parent but lacks wings and cannot reproduce.
  11. 19. The specific gas required by a germinating structure to carry out respiration and release energy before leaves appear.
  12. 20. The tough outer protective covering that protects the baby plant inside from injury and drying out.

  1. 1. Reproduction ensures the __________ of a specific species from one generation to the next, preventing extinction.
  2. 2. The structures that provide stored food to the baby plant for energy before it can make its own food.
  3. 3. A life cycle with four distinct phases of development, which is observed in butterflies, mosquitoes, and beetles.
  4. 6. The green parts that must fully develop and unfold so the young plant can finally start to make its own food.
  5. 7. The structure that grows upward toward light to support the leaves and transport water up from the roots.
  6. 11. Destructive caterpillars or beetles that feed heavily on vegetable crops, destroying leaves and reducing plant growth.
  7. 12. The essential liquid that swells the seed, splits the outer coat, and activates the food store to start growing.
  8. 13. The completely ordered sequence of stages of growth and development that a living thing goes through during its lifetime.
  9. 16. The very first structures to emerge from a germinating structure to anchor the plant and absorb water from the soil.
  10. 18. The process where an insect sheds its hard outer skin or skeleton periodically so that its body can grow larger.
  11. 20. The structural unit of a flowering plant that contains the tiny baby plant and stored food for development.
