Seed dispersal

  1. 1. Seed dispersal
  2. 2. Acorns fall from the tree and sprout • If they are not destroyed by animals, white oak acorns can sprout rapidly after falling from the tree.
  3. 3. Animal dispersal by hooked fruits • Some species of plant use hooks on their fruits to attach themselves to the fur of mammals or feathers of birds
  4. 4. Animal burial • Hard nuts are usually destroyed if chewed or eaten. • However, animals such as squirrels may store them to eat later and forget to go back to get them, giving them a chance to germinate. • On rare occasions, birds such as blue jays can transport acorns long distances.
  5. 5. Soft fruit dispersal • Fleshy fruits • The seeds of many plants are dispersed after passing through the digestive system of animals that have eaten the fleshy fruits.
  6. 6. Wind dispersal • Some plants, such as the dandelion, have seeds that act as parachutes, which are carried away by the wind
  7. 7. Plantlet reproduction • Spider plants, amongst others, send out stems which produce plantlets, these baby plants then try to root themselves
  8. 8. Spinning dispersal • Maple fruits are winged, two- seeded pods. They spin like helicopters as they fall from the tree, providing a longer time for dispersal by wind.
  9. 9. Dispersal by water • Coconuts can travel hundreds of miles by floating in the sea
