(a prokaryote is a unicellular organism that lacks a membrane-bound nucleus (‘karyon’), mitochondria, or any other membrane-bound ‘organelle’)
.
(the word prokaryote comes from the Greek πρό (pro) “before” and καρυόν (karyon) “nut or kernel”)
(‘prokaryotes’ can be divided into 2 domains, ‘archaea’ and ‘bacteria’)
(in contrast, species with ‘nuclei’ and ‘organelles’ are placed in the domain ‘Eukaryota’)
(in the ‘prokaryotes’, all the intracellular water-soluble components (‘proteins’, ‘DNA’, and ‘metabolites’) are located together in the ‘cytoplasm’ enclosed by the ‘cell membrane’, rather than in separate cellular compartments)
(‘bacteria’, however, do possess protein-based bacterial microcompartments, which are thought to act as primitive organelles enclosed in ‘protein shells’)
(some ‘prokaryotes’, such as ‘cyanobacteria’ may form large ‘colonies’)
(others, such as ‘myxobacteria’, have multicellular stages in their ‘life cycles’)
(‘molecular studies’ have provided insight into the ‘evolution’ and ‘interrelationships’ of the 3 domains of biological species)
(‘eukaryotes’ are organisms, including humans, whose cells have a well defined membrane-bound ‘nucleus’ (containing ‘chromosomal DNA’) and ‘organelles’)
(the division between ‘prokaryotes’ and ‘eukaryotes’ reflects the existence of 2 very different levels of ‘cellular organization’)
.
(distinctive types of ‘prokaryotes’ include ‘extremo-philes’ + ‘methanogens’)
(these are common in some ‘extreme environments’)
