How do water plants obtain nitrogen if it is insoluble in water?

Marine ecosystems:
Nitrogen is fixed in the photic zone by cyanobacteria who acquire it from the atmosphere (it isn't completely insoluble). The fixed Nitrogen can enter the water as Ammonia or Urea (which is soluble) and rains down to the deeper parts of the Ocean as detritus. Large Brown and Green algae, sea grasses and other plants of the ocean acquire Nitrogen from the Ammonia or Urea dissolved in the water, while organisms in the lower zones of the Ocean can filter feed Nitrogen from the detritus (these organisms are a part of the Nitrogen cycle, but are not plants obviously).
Otherwise, algae typically grow to have a significant part of their bodies reach the surface, where they can fix Nitrogen directly.
Aquatic:
Either from ammonia released by bacteria, from bacteria living in the anaerobic 'soil' beneath the water or by growing to the surface and directly fixing the Nitrogen there.

Why is nitrogen insoluble in water?
Nitrogen is insoluble in water because it does not form strong interactions with water molecules. Nitrogen is a nonpolar molecule, while water is a polar molecule. Polar molecules dissolve in water due to the attractive forces between the positive and negative ends of the molecules, but nonpolar molecules like nitrogen do not have these strong attractions and therefore do not dissolve.
Why nitrogen is sparingly soluble in water?
N2 is a very stable, nonreactive , non-polar gas so is almost insoluble in water.
How does nitrogen move from the soil into the xylem?
Nitrogen is carried from soil into the xylem of plants. Without water plants cannot get nitrogen and other nutrients from the soil. Therefore water carries out more than one function to aid in the growth of plants.
What chemical must be transformed by plants?
Nitrogen Gas
Is MnS soluble or insoluble?
Insoluble. Metallic sulfides are very poorly soluble in water.
Is nitrogen a solute?
Nitrogen is a diatomic elemental gas (79% in air) and rather insoluble in water.
Is nitrogen a solution?
Nitrogen is a diatomic elemental gas (79% in air) and rather insoluble in water.
How do plant obtain energy?
By combining Nitrogen, water, carbon dioxide, with sunlight. The sunlight gives energy to the reaction that turns water and carbon dioxide into complex hydrocarbon chains utilizing a nitrogen intermediate cycle in the conversion that is not yet fully mapped by plant biologists.thru photosynthesis. Plants absorb sunlight and convert it to chemical energy.Plants obtain energy by combining Nitrogen, water and carbon dioxide, with sunlight
What plants must obtain water with osmosis?
All Plants must obtain water by osmosis
Why is nitrogen insoluble in water?

Polar molecules dissolve in water due to the attractive forces between the positive and negative ends of the molecules, but nonpolar molecules like nitrogen do not have these strong attractions and therefore do not dissolve.
How does nitrogen get out of soil?
From lightening and nitrogen-fixing bacteria in the roots of certain plants.
Where does plants get nitrogen?
when animals eat plants,they get nitrogen compounds that their bodies need.plants do not make these nitrogen compounds. so from where do plants get their nitrogen compounds/ from the air

Where do plants obtain most of there water?
from soil.
How are Nitrates and Nitrogen different?
Nitrates are the negative ions (NO3-) of nitrate salts in solution and Nitrogen is a diatomic elemental gas (N2), 79% in fresh air, insoluble in water.
Why starch is a good storage compound in plant?
Starch is insoluble in water and so can be used as a storage device for glucose; plants convert the spare glucose into starch then store it.
