Plant Cell Organisation and Transport

• List the tissues that make up a leaf: Epidermis tissue

  Mesophyll Palisade tissue

  Spongy Mesophyll

  Xylem and Phloem

  Meristem Tissue
• Explain how the structure of the upper epidermal tissue in a leaf is related to its function.

  The upper epidermal tissue is made up of cells with a large surface area
• What is the function of the Phloem?


  Transportation of sugars and other organic nutrients in plants. This process is called Translocation
• What is transpiration?

  Loss of water from the Plant
• List the four main things that affect transpiration

  Temperature, humidity, wind speed, and light intensity.
• How could you meaure the rate of transpiration?


  Potometer

  • as the plant takes up water, the air bubble move along the scale
• Name the type of cell that help open and close stomata
