Examining mycorrhizae

From Science & Plants for Schools (SAPS), this practical activity was developed for Scottish Highers specifications, but the protocol can equally well be used for other specifications. 

Students prepare and stain roots, and then examine them to establish the frequency of mycorrhizae. 

The practical activity helps students to: 
* develop knowledge and understanding of mutualism and in particular, those benefits obtained from a mycorrhizal relationship 
* develop problem solving, experimental design and evaluation skills. 

The materials contain background information, teacher information, extensive technical guidance and students' instructions.
