Botany 431 - Physiological Plant Ecology


At the end of your study this week, you should be able to achieve the objectives listed below. You must assemble the evidence that you have achieved these learning outcomes into your Portfolio. You should provide evidence that would be regarded as performance at the top two levels of Biggs' SOLO Taxonomy.

The material in your Portfolio will be assessed as Project 2.

If you wish to discuss this material informally with your peers, you can interact in Esme's Coffee Shop.

You can also challenge your peers by posting questions for them to respond to on the Student Quiz Board.

Week Five - Learning Objectives

When you have completed this section you will be able to:

  1. Explain how the interaction between radiation, and sensible and latent heat fluxes is balanced by heat storage in chemical reactions and plant temperature changes. Remember to consider dew and frost events.

  2. Discuss the nature of the information plant and soil scientists obtain by the application of the Penman-Monteith equation.

  3. Recall from Botany 240 how the light reactions of photosynthesis are driven by the energy of photons and result in the evolution of oxygen and the synthesis of NADPH and ATP.

  4. Discuss how rates of oxygen evolution may be measured polarographically using a leaf disc electrode.
