Polymorphism in lysosomes or kinds of lysosomes :
In the same cell at different times or in different cells 4 kinds of lysosome are reported.
a) Primary lysosome or storage granule :
1. It is a newly formed lysosome. -
2. It is formed from golgi.
3. it forms from G.E.R.L, which means 'Golgi associated with Endoplasmic Reticulum will give Lysosome". This was stated by Dyson 1978.
4. This is called original lysosome.
b) Phagosome or pinosome or digestive vacuole :
1. A original lysosome units with a phagocytic or pinocync vesicle and forms a phagosome.
2. In this phagosome the food is digested.
c) Autophagic vacuole or autolysosome :
When the organism is in a state of starvation the lysosome will start digesting the cell contents. Such lysosome is called autophagic vacuole.
d) Residual body :
After the process of digestion in phagosome or autophagic vacuole some materials are not digested. Such Iysosomes with undigested food is called residual body. This residual body will send the undigested matter through plasma membrane.
In nerve and muscle cells residual bodies are more in number. They are called, "Lipofucine granules". (By the estimation of these granules the age can be decided)
The polymorphic tendency of lysosome is not real, it is connected with the digestive activity of the lysosome.

Polymorphic cell organelle is lysosome because of its different forms and functions. It contains acidic hydrolytic enzymes that break down waste materials and cellular debris.
