Seed Dispersal

What is Seed Dispersal? Why Seed Dispersal? The moving of a plant’s seed away from the parent. Why Seed Dispersal? To reduce competition

1. Wind Dispersal Seeds are very light Shaped so they are easily carried by the wind http://www2.bgfl.org/bgfl2/custom/resources_ftp/client_ftp/ks2/science/plants_pt2/wind.htm

2. Explosive Fruits suddenly burst open releasing the seeds Example: Peas http://www2.bgfl.org/bgfl2/custom/resources_ftp/client_ftp/ks2/science/plants_pt2/bursting.htm

3. Water Fruits are waterproof Fruits can float Ex: Coconuts http://www2.bgfl.org/bgfl2/custom/resources_ftp/client_ftp/ks2/science/plants_pt2/water2.htm

4. Hitchhiker Seeds have hooks on them and become attached to passing animals http://www2.bgfl.org/bgfl2/custom/resources_ftp/client_ftp/ks2/science/plants_pt2/lift.htm

5. Animal Food Seeds are enclosed in a tasty fruit Animals eat the fruit Seed passes through unharmed Ex: Blueberries http://www2.bgfl.org/bgfl2/custom/resources_ftp/client_ftp/ks2/science/plants_pt2/animal.htm

Other Drop and Roll Shakers http://www2.bgfl.org/bgfl2/custom/resources_ftp/client_ftp/ks2/science/plants_pt2/drop.htm Shakers http://www2.bgfl.org/bgfl2/custom/resources_ftp/client_ftp/ks2/science/plants_pt2/shakers.htm
