Answer 1

one of the special characteristics of microorganisms is that they cannot be seen with the naked eye other than this the characteristics of microorganisms depend on the type of the microorganism or on the group in which they are classified

Answer 2

Bacteria

Prokaryotic
Cell Walls of Peptidoglycan
Both DNA and RNA
A few are obligate parasites

Archea

Prokaryotic
Sone have cell walls-crystalline lattice made of proteins
Both DNA and RNA
No obligate parasites have been identified

Fungi

Eukaryotic
Cell walls made of chiten
Both DNA and RNA
No obligate parasites for humans, but some do exist for plants

Algae

Eukaryotic
Cell walls made of cellulose
Both DNA and RNA
No obligate parasites; organisms are photosynthetic

Protozoa

Eukaryotic
Plant-like species have cell walls made of cellulose; animal-like species do not
Both DNA and RNA
About 20 obligate parasites have been identified

Helminths

Eukaryotic
No cell walls
Both DNA and RNA
All are obligate parasites

Viruses

Acellular
No walls
Either DNA or RNA depending on genome
Obligate intracellular parasites
Cannot be grown in culture

Prions

Acellular
Non-living; tiny pieces of protein
Neither DNA nor RNA
Evidence that some may not be obligagte parasites
Cannot be readily destroyed by conventional disinfection and sterilization procedures
