Plant tissues, organs and organ systems

Cards (14)

  • 6 Plant tissues
    Epidermal
    Palisade Mesophyll
    Spongy Mesophyll
    Xylem
    Pholem
    Meristem
  • Function of Epidermal tissue

    Covers and protects leaf
  • Function of palisade mesophyll tissue

    Site of photosynthesis
  • Function of spongy mesophyll tissue 

    The site of gas exchange and phtosynthesis
  • Function of xylem tissue 

    Transport of water and dissolved ions
  • Function of Pholem tissue 

    Transport of Glucose
  • Function of meristem tissue 

    Dividing into cells at growing tips of shoots and roots
  • Three plant organs
    Leaf
    Stem
    Roots
  • Transpiration
    Movement of water from the roots to the leaves eventually leaving the leaves via evaporation
  • 4 factors affecting the rate of transpiration
    Temperature
    Humidity
    Air movement
    Light intensity
  • Translocation
    Movement of sugars from the leaves to the rest of the plant
  • Adaptation of Xylem tissue 

    Hollow tubes strengthened by lignin in the walls
  • Adaptation of Pholem tissue 

    Elongated cells with pores in the end cell walls to aid the movement of dissolved sugars.
  • Function of stomata and guard cells
    Controling gas exchange and water loss
