Coconuts are well-known travellers, as is the famous Coco-de-mer, found only on the Seychelles, but familiar before its origin was known from the giant seeds washed up on other tropical beaches. The parent plant makes the spiky little burrs from the flower. They have usually fibrous tissue for floating on water surface, and protective devices so that the embryo may not be damaged. Then the burr is carried to a new place, where animals usually try to get it off themselves. They have a hard seed coat that allows them to float down streams and rivers. Plants which grow beside water often rely on water to transport their seeds for them. Coconuts can travel for thousands of kilometres across seas and oceans. A clip from 'The Private Life of Plants' (narrated by David Attenborough) about the dispersal of plant seeds by water. The seeds then get dispersed through the animal’s droppings. Examples include burdock. Some plants even shoot the seeds out explosively. The thick floating fruits are impermeable to water and are filled with nutrients to keep the embryo alive for months at sea. These get eaten by hungry birds and other small animals. Some seeds develop into Dispersal by Animals: Edible fruits, specially those that are brightly colo­ured, are devoured by … Explanation:. Weed seed often remains viable in water for several years, creating a "floating seed bank" and allowing weeds to disperse over large areas in moving water. Two tall trees, Willow and Silver Birch, are often found in the middle of moorland, far from any other trees, but along the course of a stream.
