Morphology
function. The morphological determinations invariably require the intensive studies of the
individual
cells of a pure culture.
The microorganisms being of very small size are usually expressed in micrometers
(
μm)*.
Interestingly, the morphological characteristic features are relatively easier to analyze and study,
specifically in the
eukaryotic microorganisms as well as the more complex prokaryotes. However, the
morphological comparisons amongst the microbes play an important and vital role by virtue of the fact
that their major structural features exclusively depend upon the prevailing expression of several
genes.
In fact, they are found to be fairly stable genetically, and hence fail to undergo drastic variation in
response to the environmental alterations. Therefore, morphological similarity serves as an essential
novel indicator with regard to phylogenetic **relationship.
