Question

Answer yes or no
(1)Nitrogen is used for the synthesis of plant proteins.


(2)Atmospheric nitrogen is fixed in soil as its compounds by the
process of lightning.
​

Answer 1

Answer:

Plants get their nitrogen from the soil and not directly from the air. ... The act of breaking apart the two atoms in a nitrogen molecule is called "nitrogen fixation". Plants get the nitrogen that they need from the soil, where it has already been fixed by bacteria and archaea.

Answer 2

Answer:

1) yes

2) no

Explanation:

1) It is well established that plant roots take up nitrogen compounds of low molecular mass, including ammonium, nitrate, and amino acids. ... We show that both species can use protein as a nitrogen source for growth without assistance from other organisms.

2)Nitrogen in the atmosphere can be transformed into a plant-usable form, a process called nitrogen fixation, by lightning. ... The nitrates fall to the ground in raindrops and seep into the soil in a form that can be absorbed by plants. Lightning does add nitrogen to the soil, as nitrates dissolve in precipitation
