The granular form structurally resembles the vacuolar form except for the presence of granules in the central body and the cytoplasm [Figure 1]b. Electron microscopic studies have identified three types of granules namely metabolic, reproductory and lipid granules. The metabolic granules are exclusively found in the cytoplasm and are involved to carry out the various metabolic pathways of the organism. The reproductory granules are seen only within the central body and the suggestion of their role in schizogony is currently considered obsolete. [39],[40] The lipid granules serve as storage bodies and are seen both in the cytoplasm and in the central body. [41] The granular forms show a lesser degree of pleomorphism as compared to the vacuolar forms. The average diameter of the granular forms ranges from 15 μm to 25 μm and the largest is reported to be 80 μm. [42],[43]
