5 Matching questions

  1. abscisic acid
  2. ethylene
  3. summer solstice
  4. collenchyma
  5. phloem
  1. a vascular tissue responsible for the transport of nutrients and the carbohydrates produced by photosynthesis, alive& composed of sieve tubes with a continuous stream of cytoplasm
  2. b Day with the most hours of sunlight and the fewest hours of darkness (June 22)
  3. c stimulates stomata closure (i.e. during droughts)
  4. d plant hormone that stimulates fruits to ripen
  5. e plant cells with unevenly thickened primary cell walls that are alive at maturity and that function to support the growing stem

5 Multiple choice questions

  1. hormone that controls stem elongation along w/ auxin, triggers germination in seeds
  2. water always moves from areas of high concentration to low- created by high solute concentration and/or low pressure
  3. consist of less densely packed, light-colored spring wood, alternating with densely packed, dark-colored summer wood (made of xylem- phloem always made new annually)
  4. increase in plant LENGTH
  5. plant hormone that diffuses down from the shoot tip meristem to stimulate cell growth and elongation

5 True/False questions

  1. gravitotropismtendency of plants to grow toward a source of light b/c of the movement of auxin to the opposing side of the plant, giving that side more nutrients to grow and lean in

          

  2. root pressuresmall extensions of the roots which actively transport nutrients, causing water to come in passively. maximize surface area for absorption

          

  3. pressure-flow theoryexplanation of plant nutrient transport from leaves/photosynthetic materials to other parts of the plant driven by the pressure build-up of hypertonic solution in leaf phloem

          

  4. thigmotropismtendency of plants to grow toward a source of light b/c of the movement of auxin to the opposing side of the plant, giving that side more nutrients to grow and lean in

          

  5. translocationthe process by which evaporation at the leaf surface pulls water up the tree through xylem
