How do plants reproduce? Seed dispersal How do plants reproduce?

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. 

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

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.

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. 

Wind dispersal Some plants, such as the dandelion, have seeds that act as parachutes, which are carried away by the wind

Plantlet reproduction Spider plants, amongst others, send out stems which produce plantlets, these baby plants then try to root themselves

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.
