The fibrous husk traps the air and enables the fruit to float on water.
Fruits dispersed by water usually float and are carried along rivers, streams or at sea.
They often have waterproof coverings or fibrous husks to help them float in water.
Example: coconut, lotus plant, mangrove.
Dispersal of fruits and seeds:
-In order for seeds to grow at a suitable place, they must be scattered. Why is that so?
– When the seeds grow too closely together, overcrowding might occur.
-So the young plants may not get enough water, minerals and sunlight to grow well.
-The scattering of seeds or fruits is called dispersal.
-Plants that grow near or in water usually disperse their fruits or seeds by water.
-The fruits and seeds are able to float on water as they have special structures such as a fibrous husk or air filled spaces.
-The above picture shows the fruit of a coconut. Other fruits dispersed by water include the water lily, lotus, sea-almond and mangrove.
