How do plants grow under the sea without sun light and air?
Sunlight can extend down into the ocean up to 660 feet. In murky waters it only extends 50 feet. This zone is called the sunlit zone but it is also called the euphotic zone or epipelagic zone. Plants grow in this zone where they can get sunlight. A plant that grows in the ocean like a seaweed or kelp does not need air. If you scroll down a bit by clicking on the down arrow at the bottom right hand of your screen you will see a drawing on the left of this sunlit zone of the ocean.
Reply:the plants only can grow if sunlight can reach the leaf.so the plant can't grow on the bottom of sea.only fish and some anemon can grow there.anemon consume plankton.there are many plankton on the sea
Reply:Maybe its because of the oxygen in the water and nutrition from the underwater creatures within the habitat
Reply:Plants growing under the Sea are modified in such a way as to utilize their oxygen requirement in form of dissolved oxygen present in Water. They get little Sunlight above the benthos region in the Sea.
Reply:they have adapted and get what they need from the water, many fish inhabit the dark cold undersea as well
Reply:If you mean 'plants' in the deep sea, then the fact is that they aren't plants, but animals





Their development - fronds and all sorts of wavy bits - has led them to look like plants
Reply:Adaptation. Simply as that.

and scroll down to the section entitled "Bio-chemistry at the Vents". In the same way that land-based plants require photosynthesis, these undersea plants undergo a process called chemosynthesis.
Reply:They don't. All plants need sunlight to synthasis their food. Therefore plants do not live in waters too deep for sunlight to penetraite.





THey don't need air because water is made of hydrogen and oxygen so they get oxygen from the water.
Reply:There is actually dissolved oxygen in water. It is what fish breathe. The real question is how do land plants survive out of the water, since early plants were all aquatic.





Sunlight is necessary, it penetrates to certain depths..
Reply:the plants known as sea weeds can grow under the sea at a depth that the types of light as we know it can't reach. Sun Light is also Known as white light as is divided into the colours of the rainbow, Land plants have white light to use so the most effective colour of absorbe the sunlight is green (that is why you have green leaves), however in the sea many colours are absorbed by the water so red is a more effective colour to use.

Reply:it has always amazed me too. how do they. well. they adapt. the sunlight does actually penetrate the water, and there is oxygen , but not as we, know it....they live a happy life in the blue deep
Reply:sun light reaches plants under water, and they take oxygen from dissolved air in water just like fish dose,


that is why no much under water plants at deep waters where sun light dose not reach
Reply:thats a very good question...hmmmm
Reply:The plants depend on sunlight getting down to them (to about 200 metres) after that the plants can live. The use dissolved carbon dioxide on the sea water. The suggestion that they get their oxygen by cracking the water into oxygen and hydrogen is incorrect.
