Solution:
Prokaryotic cells contain a cell wall covering the cell membrane except in exception:mycoplasmas lack cell wall
Cytoplasm is the fluid matrix that fills the cells of prokaryotes
Absence of a well defined nucleus
Genetic material of prokaryotes is naked and not surrounded by nuclear membrane
Presence of small circular DNA in addition to the genomic DNA.The small circular DNA is called plasmids.
Absence of membrane bound cell organelles
Presence of non-membrane bound organelles like ribosomes
Presence of mesosome formed by infoldings of cell membrane
Functions of mesosome
Mesosomes are structures that help in cell wall formation,DNA replication, respiration,secretion processes,and increasing the surface area of the plasma membrane and enzymatic content.
Presence of inclusion bodies
Inclusion bodies
Reserve materials found in prokaryotic cells are stored in the cytoplasm in the form of inclusion bodies,which are not covered by any membrane system and appear free in the cytoplasm.
Examples:phosphate granules,cyanophycean granules and glycogen granules.
