6 Markers

• What are the two main types of vascular tissues in plants?

  Xylem and phloem
• What is the primary difference between the cells that make up xylem and phloem?


  Xylem is made of dead cells, while phloem is made of living cells
• Does xylem contain cytoplasm?


  No, xylem does not contain cytoplasm
• What structural feature differentiates the end walls of xylem cells from phloem cells?


  The end walls of xylem cells do not have pores, while phloem cells have pores
• What substance is found in xylem but not in phloem?


  Lignin
• What is the main function of xylem in plants?


  Xylem transports water and mineral ions
• What does phloem primarily transport?


  Phloem transports dissolved sugars
• What process is xylem involved in?


  Xylem is involved in transpiration
• What process is phloem involved in?


  Phloem is involved in translocation
• In which direction does xylem transport substances?


  Xylem moves substances in one direction
• How does phloem transport substances?


  Phloem transports substances in both directions
• What are the key differences between xylem and phloem in terms of structure and function?

  • Xylem:
  • Made of dead cells
  • No cytoplasm
  • End walls without pores
  • Contains lignin
  • Transports water and minerals
  • Involved in transpiration
  • Moves substances in one direction

  
  

  • Phloem:
  • Made of living cells
  • Contains cytoplasm
  • End walls with pores
  • Does not contain lignin
  • Transports dissolved sugars
  • Involved in translocation
  • Moves substances in both directions
