PRACTICAL PROJECT

  • SYSTEMATIC STUDIES OF A SELECTED PLANT SPECIES FROM THE CAPE FLATS NATURE RESERVE:
  • Select a plant species from the list provided and confirm your choice with me
  • Then:
  • Map the plant’s distribution in the Reserve using a GPS and a suitable application for mapping.
  • Describe the plant’s habit, distribution, classification, habitat, morphology, reproductive biology (this may be from the literature), and anything else that you think is relevant. Literature consulted must be recent.
  • Study the leaf epidermis focussing particularly on any special structural/functional features and illustrate these with suitable photographs. Also include measurements of epidermal structures, frequencies of stomata or any other structures.
  • The final results to be presented as a full report + presentation under the
  • following headings:
  • Aims, Introduction and overview of literature (literature survey)
  • Materials and methods
  • Results, Discussion, Conclusion and references
  • GPS co-ordinates (in decimal degrees) must be in Excel format and included
  • as an appendage.
