Lysosomes 1- Membranous organelles. 2- L/M: can be identified by using histochemical methods (enzymes). 3- By E.M.: rounded small membranous vesicles: a-Primary lysosomes: contain hydrolytic digestive enzymes, which are synthesized in RER, then transferred to Golgi, where lysosomes bud from. They are homogenous. b- Secondary lysosomes: are formed when primary lysosomes interact with other substance. They are heterogenous.
