  1. meristematic tissue
  2. vessel elements
  3. primary growth
  4. annual rings
  5. spring wood
  1. a 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. b Structures that, along with tracheids, make up xylem
  3. c plant tissue found only in the tips of shoots and roots; responsible for plant growth via mitosis
  4. d characterized by a light color due to rapid production of xylem in the springtime
  5. e increase in plant LENGTH

5 Multiple choice questions

  1. the solution of water and minerals that accumulates in the root xylem and flows through xylem vessels in a plant
  2. a plant's response to seasonal changes in length of night and day
  3. theory that explains how the physical properties of water allow it to move through the xylem of plants due to evaporation
  4. stimulates stomata closure (i.e. during droughts)
  5. the woody part of plants: the supporting and water/nutrient-conducting tissue, consisting primarily of tracheids and vessels. dead cells at maturity, fused end to end with perforations between

5 True/False questions

  1. root hairthe flow of water into roots at roots hairs that builds up pressure, causing upward movement at night that is significant in smaller plants (eventually opposed by gravity)


  2. short-day plantplant that generally requires short nights-- less that 10-12 hours of darkness to begin the flowering process (spring, approaching summer)


  3. gibberellinhormone that controls stem elongation along w/ auxin, triggers germination in seeds


  4. phloemvascular tissue responsible for the transport of nutrients and the carbohydrates produced by photosynthesis, alive& composed of sieve tubes with a continuous stream of cytoplasm


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