Examination of a cell by transmission electron microscopy reveals a high density of ribosomes in the cytoplasm. this observation suggests that this cell is actively producing large amounts of what molecules?

While examining a cell under transmission electron microscope, it is observed that the high density of ribosomes present in the cytoplasm produces large amounts or protein molecules. Ribosome contains rRNA and proteins. rRNA directs the catalytic process of protein synthesis.

The messenger RNA or mRNA that have the coding sequences exits from the nucleus and enters the ribosome and gets translated to form proteins. The transfer RNA or tRNA relocates amino acids from nucleus to the ribosome.

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.
