Dicotyledonous leaves

  • label from prepared slides plan diagrams of transverse sections of leaves of herbaceous dicotyledonous plants using an eyepiece graticule to showtissues in correct proportions
  • label from prepared slides the cells in the different tissues in leaves of herbaceous dicotyledonous plants using transverse and longitudinal sections
  • explain how leaves of xerophytic plants are adapted to reduce water loss by transpiration
  • explain the function of the components, tissue layers and different cell types in a dicotylyeonous leaf relate to their function in photosynthesis, gas exchange and transport of substances
  • describe and explain the structural and functional compromises between the opposing needs for effcient gas exchange and the limitation of water loss shown by xerophytic plants
