Genetic information from plants and fungi can be dispersed by the wind in the form of seeds and spores.

David Attenborough shows the birdcage plant of California as it rolls in the wind, dispersing seeds as it goes. Other examples are given, such as spores from puffball fungi dispersing in the wind. Earthstar fungi open on the woodland floor in the autumn when drops of rain cause them to explosively erupt spores. These spores are carried in the wind to a wider area to germinate.

This clip could be used periodically before each method of seed and spore dispersion is shown. Ask the students how they think the birdcage plant, the puffball and earth star fungi will spreads their seeds and spores before showing the reality.
