Across
  1. 4. of a tree- the branches and leaves
  2. 5. is made with the help of sunlight energy and chlorophyll the leaf will make sugars for
  3. 6. – circles in the wood of a tree trunk, each circle represents a year in the tree’s life
  4. 8. and mosses – green plants which begin as a spore instead of a seed the forest floor is their home they do not have flowers or coned and cannot make seeds
  5. 10. takes food down to its roots for storage
  6. 12. lighter rings of a tree are called
  7. 15. – seed coat, baby plant, stored food
  8. 17. dark rings of a tree are called
  9. 19. grow downward in search of water and minerals
  10. 20. use carbon dioxide they give off oxygen
  11. 25. – a case of many spores
  12. 26. – a gas given off by people and animals that plants need
  13. 27. – single cell that is able to reproduce living organisms
  14. 28. – to refill
  15. 31. is like a shell that protects the plant from drying out or being crushed
  16. 33. helps keep our air clean, provides lumber, and bears fruit to eat

  18. 39. is the skin of the tree that protects the sapwood
  19. 40. – the act of moving pollen from one part of the flower to another, or from one flower to another so that the flower can make seeds
  20. 41. of a tree – the stem
  21. 42. – the green material in plants
  22. 44. are dormant or resting
  23. 46. – a forest containing many needled trees bearing cones
  24. 47. the part of a flowering plant that holds and protects the seed
Down
  1. 1. and bacteria- plant like organisms that cannot make their own food because they do not have chlorophyll
  2. 2. – the yellow powdery dust formed by the flower
  3. 3. is a soil builder
  4. 7. are able to reproduce because of God’s wise design
  5. 9. are the root's mouth – they absorb the water and minerals from the soil and send them through the stem to all parts of the plant
  6. 11. needs water, the right temperature, and air to sprout
  7. 13. plants have seeds
  8. 14. – an organism that helps to break down dead things
  9. 16. trees leaves are called needles
  10. 18. – the part of a plant that holds the plant in the ground and absorbs water and minerals from the soil
  11. 19. – to make more of the same kind
  12. 20. – the food making process in green plants
  13. 21. When a leaf breaks down it
  14. 22. – a forest that grows in the temperate climate with leaves that change by seasons
  15. 23. – a forest that grows in tropical climates
  16. 24. can only come from life
  17. 29. things depend on plants
  18. 30. the part of the plant that holds the plant up; carries water and minerals upward and food downward
  19. 32. is what a baby plant depends on till it breaks through the soil and can produce its own food
  20. 34. – a living thing
  21. 36. the smallest part of an organism
  22. 37. and worms break down decaying dead things these animals are called decomposers
  23. 38. – to rest
  24. 43. – the part of the plant that makes seeds
  25. 45. – the part of the plant that makes food
