Thank you for the opportunity to help you with your question!
Microbes are characterized by direct examination with the light magnifying instrument through its morphology and total.
The essential structures are circles (coccus) and round-finished barrels (bacillus). However, there may be others, for example, helically turned barrels (spirochetes), chambers bended in one plane (Selenomonads) and irregular morphologies, (for example, the square Archaea Haloquadratum). They likewise acclimate diplos, tetrads, staphylos, streptos, palizadas and so forth.
Please let me know if you need any clarification. I'm always happy to answer your questions.
