Key Points :

It contains DNA, contains ribosomes and lacks nucleus.

Explanation: The prokaryotes are the primitive cells that were found during the primitive time. There are certain organelles that is found in the eukaryotes are absent in prokaryotes.

Their body is simpler as compared to that of eukaryotes. The prokaryotes contains DNA dissolved in the cytoplasm.

The Prokaryotes lacks nucleus and contains ribosomes that is required for protein synthesis.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
