Across
  1. 2. clear waxy coating on the surface of the leaf
  2. 3. area on stem where the leaf or petiole attaches
  3. 6. the part of the seed that is food for the developing embryo
  4. 7. control the opening and closing of the stomata
  5. 12. a straight tapering root growing vertically downward
  6. 14. the process in which plants use sugars and oxygen to produce CO2, water and ATP
  7. 16. the process where plants absorb water through the roots and then give off water vapor through pores in their leaves
  8. 18. area on stem between the nodes
  9. 20. water attracted to other substances
  10. 21. thin, branching roots growing from the stem
  11. 22. the pollination of a flower by pollen from the same flower
  12. 23. the process of converting light energy into chemical energy
  13. 25. support for the plant body
  14. 27. the undifferentiated plant tissue from which new root cells are formed
  15. 30. male and female parts of a flower on the same plant
  16. 31. structure which attaches the leaf to the stem
  17. 32. embryonic leaf or leaves of a plant
  18. 33. the undifferentiated plant tissue from which new shoot cells are formed
  19. 35. cells inside leaf where oxygen and carbon dioxide are exchanged
  20. 36. the protective end cover of a root; protects apical meristem
Down
  1. 1. male and female parts of a flower on different plants
  2. 4. embryo has two cotyledons
  3. 5. thin flat section of the leaf
  4. 8. a bud that grows from the axil of a leaf and may develop into a branch or flower
  5. 9. the fusion of male and female gametes to form a zygote
  6. 10. absorbs and transports water and nutrients
  7. 11. the transfer of pollen from an anther of a flower of one plant to a stigma of a flower of another plant of the same species
  8. 13. gives roots more surface area
  9. 15. a root that arises from an organ other than the root—usually a stem
  10. 17. cells inside the leaf where much of the photosynthesis occurs
  11. 19. the process by which pollen is transferred to the female reproductive organs of a plant
  12. 24. site of gas exchange from leaf to outer environment
  13. 26. embryo has single cotyledon
  14. 27. the end or terminal portion of the root
  15. 28. the part of the seed that develops into a plant
  16. 29. water attracted to water
  17. 34. main site of photosynthesis
