transpiration and translocation (B.24)

• Name the process by which glucose is moved from a leaf to other parts of the cell

  translocation
• what is the scientific name given to the evaporation of water from a leaf

  Transpiration
• on which side of the leaf are there more stomata?

  underside/Lower
• what is covering the top layer of the leaf to reduce the loss of water?

  Waxy Cuticle
• which organ in a plant does water enter through?

  root
• do guard cells become flaccid or turgid when it is very sunny?

  Turgid
• Do stomata open or close when it is night time ?

  Close
• describe the structure of xylem

  Hollows tubes strengthened with lignin
• structure of phloem

  Elongated cells with a sieve plate and companion cell
• four factors that increase the rate of transpiration

  1)High wind intensity 2)High light intensity 3)arid(dry) 4)high temperature
• why does high wind intensity increase transpiration?

  increases concentration gradient
• why does high light intensity increase transpiration?

  causes stomata to open
• why does arid conditions increase the rate of transpiration?

  increase concentration gradient
• why does high temperature increase the rate of transpiration?

  water particles have more kinetic energy
