Why is cellular differentiation
important for the development of a fully formed human infant?

Cellular differentiation is necessary for the development of a fully formed human infants because cellular differentiation leads to the formation of different tissues and organs which are required for the development of human infant. Without tissues and organs our body cannot function properly.

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.
