Question

what is the role of nitrogen in plants? How do plants obtain it?

P.S. = please give answer in points ​

Answer 1

Here is a look at Nitrogen's functions in plants:

• Nitrogen is an essential element of all the amino acids in plant structures which are the building blocks of plant proteins, important in the growth and development of vital plant tissues and cells like the cell membranes and chlorophyll.

• Nitrogen is a component of nucleic acid that forms DNA a genetic material significant in the transfer of certain crop traits and characteristics that aid in plant survival. It also helps hold the genetic code in the plant nucleus.

• Chlorophyll being an organelle essential for carbohydrate formation by photosynthesis and a substance that gives the plant their green color, nitrogen is a component in it that aids in enhancing these features.

• Nitrogen is essential in plant processes such as photosynthesis. Thus, plants with sufficient nitrogen will experience high rates of photosynthesis and typically exhibit vigorous plant growth and development.

2nd part of the question:

Most abundant gas in the atmosphere is nitrogen but it is a very stable form and cannot be used by plants directly. Most of the plants absorb nitrogen from the soil as nitrates and then internally convert it to nitrite and ammonium forms. The process of conversion of nitrate to ammonium form in plants is called nitrate assimilation.
