Question

which organelle is known as polymorphic cell organelle?

Answer 1

Thanks for asking the question.
Lysosomes are known as polymorphic cell organelles. Actually polymorphism is the occurrence in several different shapes particularly in reference to species or genetic variation. Lysosomes occur in more then one forms inside the cell.
The polymorphism of lysosomes can be explained on the basis of the types of lysosomes:
1.Primary lysosomes:
 They are small, newly formed structures formed in golgi apparatus, and they contain inactive enzymes.
2.Secondary lysosomes: 
They are formed when phagosomes fuse with already present primary lysosomes. Unlike primary lysosomes, they have enzymes against the material which is to be digested, and this is the function of lysosome.
3.Residual bodies:
They are formed from digestive and autophagic vacuoles and contains undigested materials
4.Autophagic vacuoles:
They are formed by union of primary lysosome around dead/dead organelles. and digest them by autodigestion.
Hope I helped.
