Lesson 1

• Plant transports food, water, and minerals through its system
• What are the two types of transport system in plants?

  Xylem and Phloem
• What cells does xylem have in its tracheary elements?

  Tracheids and Vessel Members
• What does this step implicates?

  1. Water absorbed by roots
  2. Water travels up through plant
  3. Water vapor lost from leaf pores in transpiration

  Transpiration
• As translocation happens, the water in xylem diffuses into the phloem and pushes the sugar from source to sink (stem). What happens to the pressure in stem?

  The pressure decreases.
