5 Matching questions

  1. phytochrome
  2. root hair
  3. abscisic acid
  4. phloem sap
  5. photoperiodism
  1. a a mixture of sugar, nutrients, and water that flows through phloem vessels in a plant
  2. b small extensions of the roots which actively transport nutrients, causing water to come in passively. maximize surface area for absorption
  3. c a plant's response to seasonal changes in length of night and day
  4. d Light receptor pigment in photoperiodism. Pr (red-light absorbing) vs Pfr (infrared light absorbing) In short-day plants, it stops flowering but in long-day plants it induces flowering
  5. e stimulates stomata closure (i.e. during droughts)

5 Multiple choice questions

  1. the process of moving sugars through phloem
  2. produces outer protective layer of the bark
  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. inclination to for plants to grow towards gravity
    -negative in shoots (upward growth)
    -positive in roots (downward growth)
  5. plant hormone that diffuses down from the shoot tip meristem to stimulate cell growth and elongation

5 True/False questions

  1. spring woodcharacterized by dark color due to densely packed xylem produced in the summertime


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


  3. primary growthincrease in plant LENGTH


  4. winter solsticeDay with the most hours of sunlight and the fewest hours of darkness (June 22)


  5. lateral meristema meristem that thickens the roots and shoots of woody plants, contributing to secondary growth i.e. vascular cambium and cork cambium
