Differences between prokaryotes and eukaryotes characteristics prokaryotic eukaryotic DNA with in a nuclear membrane NO yes Mitotic division DNA associated with histones Chromosome number Most 1 More than 1 Membrane bound organelles, such as mitochondria and lysosomes Size of ribosome 70S 80S peptidoglycan No

Differences between bacteria and archaebacteria Eubacteria (with the exception of the genera Mycoplasma and Chlamydia) possess peptidoglycan (synonyms: murein, mucopeptide, cell wall skeleton). The 16S rRNAs of the two bacterial kingdoms are quite distinct in sequence.

What is Microorganisms Microorganisms are creatures that are not directly visible to the unaided eye, with dramatical biologic diversity. Viruses , bacteria, fungi, protozoa and some algae are all in this category All with the exception of plants and animals

Microorganisms and Human Beings Beneficial activities: Most microbes are of benefit to human beings, some are necessary( nitrogen, carbon cycles, etc) Harmful activities: A portion of microbes cause diseases and are poisonous to human, and these are really that concern us in the study of medical microbiology, etc.

Microbiology Microbiology is the biology of microorganisms. It is a bioscience for the study of the evolution, Classification , morphology, physiology, genetics, ecology of microbes under certain definite conditions, The law of their life activities, and their interaction with human being, animals or plants as well as with natural environment.
