Difference between polymorphism and pleomorphism (golgi bodies are pleomorphic while lysosome is polymorphic) note:xplain mentioning golgi and lysosome

Dear Student,

Polymorphism means the co-existence of two or more different forms in the same cell.  Lysosomes are polymorphic means they have different size and internal structure. There are four types of lysosomes depending upon their morphology and function namely primary lysosomes, secondary lysosomes, residual bodies and autophagic vacuoles.
(a) Primary lysosomes: These are newly pinched off vesicles from the Golgi apparatus which fuse with some endosome to become fully functional. These are small in size and contain hydrolytic enzymes in the form of granules.
(b) Secondary lysosomes: They are also called digestive vacuoles. A secondary lysosome is formed by the fusion of food containing phagosome with lysosome.
(c) Residual bodies: They are those lysosomes in which only indigestible food materials have been left. The residual bodies or lysosomes pass outwardly and fuse with the plasma membrane to throw out the debris into the external environment by exocytosis.
(d) Autophagic vacuoles: They are produced by the fusion of a number of primary lysosomes around worn out or degenerate intracellular organelles.

Pleomorphism means the occurrence of more than one structural form during the whole life cycle of a cell or an organism. The Golgi apparatus is pleomorphic as it changes its shape or form according to the cell type. It can appear in three different structures namely cisternae, tubules, and vesicles.
a) Cisternae: It is a flattened membrane disk that makes up the Golgi apparatus. 3 to 7 cisternae stacked upon each other like a stack of dinner plates.
b) Tubules: Tubules connect the adjacent stacks of Golgi apparatus and form a tubular reticulate structure.
c) Vesicles: These are responsible for the transport of proteins and lipids from Golgi to other parts of the cell.
