How are microorganisms classified?

Answer 1

Living creatures are divided into two key groups: the prokaryotes, where the DNA in their cells is not enclosed in a membrane-bound nucleus and the eukaryotes where the cells do have their DNA enclosed in a nucleus and often contain other membrane-bound organelles as well. The eukaryotes include fungi, protozoa, algae, plants and all multicellular animals. Prokaryotes include bacteria and the mysterious archaebacteria which are prokaryotic in general structure but also share some characteristics with eukaryotes. Viruses are akaryotic because they are non-cellular.

Answer 2

microorganism are classified on the basis of their cell structure like first broad classification is prokaryotic and eukaryotic microbes then they classified on the bases of their habitat and physiology

Answer 3

In general, foodborne microbes are generally classified by how they contaminate food or whether they are biological agents or pathogens (viruses, bacteria, parasites, prions); chemical agents (toxins, metals); or physical agents.

Answer 4

Microorganisms are classified based on their shared characteristics and evolutionary relationships. They are grouped into categories such as bacteria, archaea, fungi, protists, and viruses. Taxonomic characteristics used for classification include cell structure, metabolism, reproduction, and genetic material.
