- sources: Spinach , Black beans , Nuts, Soy milk , Yogurt, And Seafood
- orange juice, bananas, potatoes, honeydew melon, and avocados
- regulation of the stomatal apparatus
- ATP, NAD, NADP, phospholipids, nucleic acids
- required by CAM plants and C4 plants
- needed by the Rhizobium symbionts of legumes for nitrogen fixation
- part of the cell wall of a number of land plants, including Equisetum, tomato and many grasses
- mineral ion as salts. The salts will dissolve in water, and the oppositely charged ions in the salts will separate from each other. examples: ammonium sulfate, ammonium nitrate, magnesium sulfate (Epsom salts)
- the essential elements are present in organic molecules. Decomposers in soil break down the organic material and release the essential elements into solution. Organic fertilizers tend to be slow release fertilizes. Also, a healthy soil with lots of decomposers is necessary in order for the nutrients to be released.
- Nitrogen Assimilation: actual incorporation of ammonium into organic molecules in the plant body.
- Nitrogen Reduction: the process of reducting nitrogen in the nitrate ion, NO3-, from an oxidation state of +5 to the -3 oxidation state of ammonium.
- Nitrogen Metabolism: consists of: 1. nitrogen fixation, 2. nitrogen reduction, and 3. nitrogen assimilation.
- Nitrogen Fixation: is the conversion of N3 gas into nitrate, nitrite, or ammonium.
- a single element is supplied to a plant in excessive quantities or withheld from it.
- chemical composition is carefully controlled
