Plants have adapt many different ways to spread seeds around their ecosystem in rescript to reproduce and out compete other plants that arise within the same conditions . for plants that survive in or next to body of water , float is a distinctive method for seed dispersal . Some seeds have the power to swim for C or thousands of miles in lookup of new stead to arise .
Coconut
The coconut palm , Cocos nucifera , is mayhap the best known plant that has a float seeded player . Floating through the ocean is the primary way coconut tree palms have spread throughout the isolated island of the tropics and colonise almost every beach in the world that does n’t encounter a frost . The large nuts have an on board air pocket in the center cavity that makes them very buoyant and they have their own supplying of fresh body of water in the form of coconut milk to keep them hydrated under the pressures of the intense tropical sun and salt water . The thick outer husk protects a coconut from poke undulation and rocky seashores . A coconut tree can float for up to one year before it last rests on a desirable space , germinates and commence to grow a new tree .
Mangroves
Rhizophora mangle are the single most crucial trees for the health and sustainability of tropic and semitropical intertidal zones where fresh water debilitate into a saltwater estuary or Strategic Arms Limitation Talks marsh on the bound of the ocean . Very few trees are able to tolerate the changing salinity of the water as the tide do in and out . Red mangrove , Rhizophora mangle , are key to prevent erosion from hurricanes and create raw land masses on sandbars and coral reefs as the forest grow outwards . The tree diagram forge almost dense jungles right in the water and along the shore providing a full of life glasshouse habitat for many small-scale fish , fry , and invertebrates that feed a coral reef .
The seed of the red Rhizophora mangle germinates on the tree after pollination and grows a modified etymon from the bottom of the seed that is called a propagule . When advanced , this fall off the tree into the water and can float in full oceanic salt pee for up to a class before it lands and take root and starts to turn a new tree . This has permit mangrove to spread around the world , usually in conjunction with coral reef .
Blue Lotus
The blue lotus has been a staple in westerly mythology since before write existed . Ancient Egyptians prized the flower as a symbol of the creation of the universe and for it ’s gently psychoactive properties . These flowers are said to be what the drunk Lotus Eaters were exhaust in Grecian mythology .
The blue lotus , Nymphaea nouchali var . caerulea , is native to the Nile river in Africa but has been spread around the world . Like many other species of Nymphaea , after pollenation the bloom sinks to the bottom and grows a pear shaped fruit full of thousands of small seeds . When ripe , the seeds are released and all are one by one wrap within a thin membrane that holds aviation pockets allow them to be adrift up and away from the parent flora . After a few days the tissue layer disintegrates and the seeds sink to the substratum in another part of the river or pool where they germinate and grow a new lotus plant .
