Prokaryote

Prokaryotes form the superstructure of primordial nuclear organisms. We classify domains as prokaryotes:
 * Archea
 * Bacteria

Bacteria
These are the simplest organisms that can be considered alive according to cell theory and the definition of life. Bacteria are widespread cosmopolitanly. Today, a huge number of species are known. From a medical point of view, only a very small part is important, which can be the cause of infectious diseases for humans.

Cyanophyta (Cyanobacteria)
They are developmentally on the same level as bacteria. They are prokaryotic, autotrophic organisms with non-membrane organelles (tylakoids), which contain chlorophyll, phycocyanin and other dyes used in photosynthesis. They live in water and in humid places. They were probably the first source of O2 in the Earth's atmosphere.
