Document Summary
Microbes consist of organisms that are too small to be seen clearly without a microscope (a. k. a. microorganisms). Prokaryotes, which range in size from 0. 2-10 micrometers in diameter. and. Unicellular eukaryotic organisms of the kingdom protista that are in the. The period at the end of this sentence is about 1/2 millimeter (500 micrometers) in diameter. There are groups of biological entities that are even smaller than bacteria. These groups are, viruses, viroids, and prions for being alive. Some are things that can make organisms sick. These are not organisms, because they don"t have all the requirements. A virus particle is small (0. 05 - 0. 2 micrometers) and comes in many capsid - a protein coat that surrounds and protects the genome. A membrane (phospholipid bilayer) that surrounds the capsid genome - the genetic information can be either dna or rna (ds or ss)
