Section A

  1. Describe the main differences between dicot and monocot plants with reference to the origins and subsequent evolution of both groups of plants. Use well-labelled diagrams to illustrate your answer.
  2. Explain what is meant by polyploidy and discuss (using illustrated examples) how it is important to plant evolution and crop improvement.
  3. Using examples and illustrations, write an essay on what is meant by centres of diversity and centres of origin of crop plants and discuss the implications of major geographic movements of crops, including the Colombian exchange.
  4. Briefly discuss the Irish tree flora in a European context, with particular reference to evidence for postglacial tree colonisation and the origins and routes of this colonisation.

Section B

  1. a) Draw a phylogenetic tree that represents our current understanding of evolutionary relationships among charophycean green algae, the 3 groups of bryophytes and ferns. Label each branch point with a derived character that is unique to the group descended from the common ancestor. b) Choose one group of bryophytes to illustrate the general life cycle and refer to the gametophyte and sporophyte stages and structures therein. Be sure to indicate which stages are haploid and which are diploid
  2. With reference to pollination mechanisms, describe what is meant by ‘advanced’ floral structures. Illustrate your answer with examples you are familiar with.
  3. Give an illustrated account of diversity in the Gymnosperms.
  4. Write concise notes on two of the following: a) Pteridophyte life cycles and classification b) the Gramineae (Poaceae) c) Wind pollination.
