  25. Phototropism
    growth with respect to direction of light
  26. Define auxin.
    plant hormone that influences many plant functions like phototropism, apical dominance, and root branching; generally stimulates cell elongation and cell division and differentiation
  27. Function of ethylene?
    promotes the ripening of fruits and the dropping of fruit and leaves
  28. Function of abscisic acid?
    inhibits the action of other hormones, enforcing dormancy in seeds and buds and causing the closing of stomata

    • monocot
    • spurge family
  30. Spinach is what kind of plant?
  31. Salicylic acid plays what role in plants?
    roles in plant growth and development, photosynthesis, transpiration, ion uptake and transport. SA also induces specific changes in leaf anatomy and chloroplast structure. SA is involved in endogenous signaling, mediating in plant defense against pathogens.[4] It plays a role in the resistance to pathogens by inducing the production of pathogenesis-related proteins.[5] It is involved in the systemic acquired resistance (SAR) in which a pathogenic attack on one part of the plant induces resistance in other parts. The signal can also move to nearby plants by salicyclic acid being converted to the volatile ester, methyl salicylate.
  32. What causes a venus fly trap to close?
    • the trigger hairs are brushed
    • Cells in an inner layer of the leaf are very compressed. This creates tension in the plant tissue that holds the trap open.
    • Mechanical movement of the trigger hairs puts into motion ATP-driven changes in water pressure within these cells.
    • The cells are driven to expand by the increasing water pressure, and the trap closes as the plant tissue relaxes.
  33. What happens to fruit when the seeds mature?
    the fruit ripens - softer, sweeter, and more bright
  34. What provides greatest means of seed dispersal?
    animal dispersal
  35. Alternations of generations.
    life cycle typical of plants in which a diploid sporophyte generation alternates with a haploid gametophyte generation
  36. Double fertilization
    in flowering plants, the fusion of two sperm nuclei with the nuclei of two cells of the female gametophyte. one sperm fuses with the egg to form zygote; second sperm fuses with two haploid nuclei of primary endosperm to form triploid endosperm cell
  37. Secondary xylem and secondary phloem
    • 2xylem - produced from cells that arise at the inside of the vascular cambium
    • 2phloem - produced from cells that arise at the outside of the vascular cambium
  38. What is older, nonfunctional xylem called?
  39. Define transpiration?
    evaporation of water through the stomata of a leaf
  40. Dicots
    flowering plant characterized by embryos with two cotyledons, or seed leaves, modified for food storage
  41. What makes plants grow tall?
    primary growth pgs.328-332
  42. Primary growth
    growth in length and development of the initial structures of plant roots and shoots, due to the cell division of apical meristems and differentiation of the daughter cells.
