Cooperation and trade are common in the natural world. Based on the cost of production and the constraints presented by the environment, an organism may be more successful by trading for a product than producing it. In this situation the organism may specialize in one product and trade for another. In this assignment we will examine an example of trading partners, mycorrhizal fungi and plants, and compare it to the principles of international trade, an important component of macroeconomics. After you view this tutorial, consider some of the principles it introduced and how they apply to specialization and trade between the symbiotic partners that make up a mycorrhizal association.
Scientists believe that this symbiosis may have been key to plants' success on land. Begin your introduction to this symbiosis at the Compost Gardener, and be sure to view their video. Next, proceed to this site maintained by the University of Western Australia, School of Plant Biology: http://mycorrhizas.info/vam.html to complete your research and locate important images for your assignment.
Using the resources provided above, develop a PowerPoint presentation that includes the following:
Compose a brief overview of the structure and function of plant roots. Include definitions and images of these terms: epidermis, exodermis, cortex, endodermis, and root hairs. You can refer to the following resource:
Provide an explanation of the symbiosis between mycorrhizal fungi and plant roots. Include definitions and explanation of the differences between Arbuscular mycorrhiza and Ectomycorrhizal fungi using the following images:
