Structure - Function

• Structure (e.g., stem, branches, leaves, vessels,
  roots, cells, etc.) and function (e.g., growth,
  development, reproduction, gas exchange, nutrient
  and water uptake, etc.) are linked.

7
Structure Function cont.

• Concept There is a strong interaction between
  the structure or form of a part/organism and its
  function (how it carries out processes)
• Example, stems, branches and twigs are arranged
  in such a way so as to
• Maximize light capture
• Minimize self-shading
• Minimize carbon costs
• Minimize hydraulic connections

Question of Optimization of structure and function
8
Structure-Function cont.

• Why might optimization of structure and function
  not occur?
• Trait or attribute not critical
• Trait or attribute linked to some other trait or
  attribute
• Architectural or ancestral constraints (e.g., a
  pine tree vs. true fir or an oak)

Where does structure or form come from?

• What are some classical examples of
  structure-functional relationships?
• Sun-shade foliage
• Canopy architecture
