Characteristics for the different types of seed dispersal
Seed Dispersal by wind
Dandelion seeds use their light and feathery structures to stay afloat in the air Maple seeds are aided by their light and wing- like structures.4Seed dispersal by water
The coconut , which has a fibrous husk and can float on water with air sacs that contain air, disperses its seeds by water.The pong pong disperses its seeds with its ability to float on water.6Seed dispersal by animals
The sandburs fruits have hooks that cling on to passing animals and humans.2. The rambutan is juicy and colourful so it is eaten by animals.

The hooks on this plant cling onto passing animals and socks.The colour and juicy flesh of rambutans attract predators.
Seed dispersal by splitting/ explosive action
1. The river tamarind has a hard exterior which bursts open when the fruit is ripe.2. The ladys finger has a pericarp, which is a lining along the walls of the fruit, which cracks, causing the ladys finger fruit to burst open.3. The african tulip works like the river tamarind.
