5 Matching questions

  1. root hair
  2. spring wood
  3. ethylene
  4. "source to sink"
  5. cohesion
  1. a characterized by a light color due to rapid production of xylem in the springtime
  2. b refers to the hydrogen-bonding between water molecules to make a chain of water from leaf to roots
  3. c small extensions of the roots which actively transport nutrients, causing water to come in passively. maximize surface area for absorption
  4. d phloem moves sugars from where they are made to where they are needed. This can be referred to as movement from ______ to _______
  5. e plant hormone that stimulates fruits to ripen

5 Multiple choice questions

  1. 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)
  2. tendency 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
  3. explanation 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. plant that blooms in response to temperature, water, etc. and not night/day i.e. desert plants, rainforests
  5. plant that generally requires long nights-- 12 or more hours of darkness to begin the flowering process (fall, approaching winter)

5 True/False questions

  1. cohesion-tension 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

          

  2. vascular cambiumproduces new xylem and phloem in stems

          

  3. parenchymatraditional plant cells with primary cell walls that are thin and flexible and that lack secondary cell walls

          

  4. phloem sapthe solution of water and minerals that accumulates in the root xylem and flows through xylem vessels in a plant

          

  5. meristematic tissueplant tissue found only in the tips of shoots and roots; responsible for plant growth via mitosis
