At various locations within the endomembrane system, flattened stacks of membranes are found. These structures are called Golgi bodies. These are discovered by Camillo Golgi in 1989. It is present in all eukaryotic cells. In plants, these are scattered irregularly in the cytoplasm and called as "dictyosomes". These are absent in bacteria, blue-green algae, RBCs, spermatozoa of bryophytes and pteridophytes and sieve tubes of phloem of angiosperm.
