Transpiration and Translocation

• Translocation:

  Transport of sugars
• Transpiration:

  The loss of water vapour
• What do the pores do?

  Enable the movement of cell sap
• Can phloem transport substances up and down? True or False

  True
• What is the xylem tube made out of?

  Dead Xylem Cells
• The Xylem is a long _______ ____

  Hollow Tube
• What is the Xylem tube strengthened by?

  Lignin
• What does the xylem transport?

  Water and mineral ions from the roots
• What are the four factors that can affect transipration?

  Light Intensity

  Temperature

  Air Flow

  Humidity
• If the light intensity (for transpiration) is bright what happens?

  More photosynthesis

  More stomata open

  Higher rate of transpiration
• If temperature (for transpiration) is higher what happens?

  higher the rate of transpiration

  (Water has more energy)
• If the Air Flow is high (for transpiration) what happens?

  Increased transpiration

  Concentration gradient is higher
• If the air is humid (for transpiration) what happens?

  Decrease the rate of transpiration

  Decrease the concentration gradient
