Across
- 3. the arrangement of leaves on the stem of a plant
- 4. the parts of a plant (such as flowers, fruits, and seeds) involved in reproduction
- 6. primary portion of the leaf
- 9. tightly packed parenchyma tissue that absorbs the majority of light energy used by the plant
- 11. have 1 cotyledon, parallel venation, scattered vascular bundles, fibrous roots, and petals in groups of 3 or 6
- 13. pattern of veins in a leaf
- 15. have 2 cotyledons, netted venation, vascular bundles on outer edge of stem, taproot, and petal groups of 4 or 5
- 16. pigments that have different colors depending on the pH of the leaf tissue—can be blue, purple, or pink
- 18. pigments in some plants that are usually yellow or orange
- 19. process of cutting away a ring of inner & outer bark all the way around a tree trunk
- 20. causes brown color in leaves that have no pigment other than chlorophyll
- 21. nonliving vascular tissue that carries water and dissolved minerals from the roots of a plant to its leaves
- 22. loses its leaves for winter
- 23. in alternation of generations, the generation that occupies the largest portion of the life cycle
- 24. makes most leaves green, allows plants to absorb energy from the sun necessary for photosynthesis
- 26. a “seed leaf” that develops as a part of the seed. It provides nutrients to the developing seedling & eventually becomes the 1st leaf of the plant
- 27. flank each stoma (sing. of stomata), to open & close it; contain chlorophyll & produce special sugars to open or close stoma
Down
- 1. a life cycle in which there is both a multicellular diploid form & a multicellular haploid form
- 2. grow year after year
- 5. cells that have not specialized in any particular function
- 7. living vascular tissue that carries sugar and organic substances throughout a plant
- 8. characteristics of the leaf edge
- 10. just above root cap, where undifferentiated cells carry on mitosis—where most growth occurs
- 12. loosely packed, at bottom of the leaf, allows lots of room for carbon dioxide
- 14. live for only 1 year
- 17. parts of a plant (such as stems, roots, leaves) that are not involved in reproduction
- 25. a fine dust that contains the sperm of seed-making plants
