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 3.

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.

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

1. Describe the influence of latitude, altitude and season on the local flux of UV-B irradiance.

2. Analyse the effects of UV-B radiation on the biology of plants.

3. Evaluate the strategies used by plants to resist the effects of strains induced by UV-B irradiance.
