Specialised Plant Cells
  1. Palisade Mesophyll Cells
    1. Characteristics
      1. Found in upper part of the leaf
        1. Column like cells packed with many chloroplasts
        2. Function
          1. Traps sunlight
        3. Root Hair Cell
          1. Characteristics
            1. Long extension protruding out into the soil
              1. Found in the young root
              2. Function
                1. Increases surface area so that it can absorb max. water and minerals
              3. Xylem
                1. Characteristics
                  1. Found in the stem, leaves and roots
                    1. Hardened cell wall
                      1. Hollow with no living contents
                      2. Function
                        1. Transports water and mineral ions
                          1. Hardened cell wall gives strength supporting the plant
                        2. Phloem
                          1. Characteristics
                            1. End walls of cells perforated (pierced; make small holes in)
                              1. Found in the stems, leaves and roots
                                1. Largely hollow inside with small living cells beside them
                                2. Function
                                  1. Allows sugars to move through the plant and the living cells provide energy for the transport
