Characteristics of prokaryotic cells are as follows
(i) A prokaryotic cell, i.e., of bacteria is surrounded by a cell membrane. The cell wall in turn is surrounded by a slimy layer.
(ii) Absence of well organised chloroplast, mitochondria and nucleus.
(iii) Nucleolus is absent. It is known as nucleoid. The DNA of a prokaryotic cell is circular and not associated with basic proteins.
(iv) The cytoplasm is filled with dense granules. Most of these granules are ribosomes.
(v) A prokaryotic cell possess single chromosome (not paired) that exists as circular loops of DNA
without histone proteins.
