Activity 5: Inquiring Further
1. Investigating allelopathy
Let students know that allelochemicals can be found in leaves, roots, stems, flowers, and fruits of plant. Leaves are the major source in most species.
The roots generally produce smaller quantities and the compounds are less
toxic than those found in the leaves. They will need to know this in order
to design an experiment.
2. Invasive species
As mentioned earlier, the government maintains extensive databases on invasive species. These databases are easily accessible by the Internet. Some of these databases are regional in scope. Students can use these databases to find the names of invasive species in their area.
